​Can you apply Lean principles to Scrum?​
Canyouapplyleantoscrum.jpgThis was another question from our recent webinar Learning the hard parts of agile software development.

Our opinion is that you can absolutely apply Lean principles to Scrum and most other agile approaches. Lean and Agile are two mindsets, but they are often seen as overlapping.

Lean and Scrum together
An agile mindset is about change management and adapting to that change, with ideas around quick delivery cycles. Lean is about minimising waste and doing the least possible effort to get the required result and the required quality. The two work hand-in-hand quite well.

In terms of applying Lean to Scrum it is about identifying the areas of potential waste. For example, doing the minimum amount of design upfront, to identify the smallest amount of work you need to do for each item, before entering into a Scrum sprint. This then continues into other areas – the right amount of analysis, the right amount of development, the right amount of testing.

Beware not to use this as an excuse for not doing things properly. Lean also places a strong focus on quality and minimising defect rates as rework is also another form of waste. So there is a need to identify the required level of functionality, quality and consistency, and then do the right amount of work to deliver that and nothing more.

How do we apply Lean principles to Scrum at Equinox IT?
At Equinox IT we do not use pure Scrum, but there are a lot of good ideas and practices in Scrum and we do use many of these, including planning meetings, daily stand-ups, cross-functional teams, co-location, retrospectives and review meetings.

In theory if you follow Scrum properly, you can’t alter it. This purest approach didn’t work for the pragmatic culture at Equinox IT, where we have always been focused on right-sizing approaches to our needs, our clients’ needs and the realities of New Zealand project conditions. In this way we do follow an approach of Scrumbut (as in “we follow Scrum… but”). While Scrumbut can have a negative connotation, done well we believe working this way has many merits. Because we also enhance Scrum with Kanban, Scrumban could also be used to describe the flavour of our approach.

One of the reasons we don’t follow pure Scrum is that the fit to the nature of our work was not a perfect match. One of the great benefits of Scrum is the ability to release at the end of sprints, and this works well when there are real deadlines from each sprint, but is an artificial timebox otherwise. For the client work that we do, delivering after each sprint doesn’t really mean a great deal to our clients. Clients can often expect a single release on a required date, so for this situation we find that Kanban works well. In Kanban we work to a realistic timeline, measure our progress and make projections, yet we do still work in tight iterations and small batches

We also subscribe to the Lean principle of continuous improvement. This is hard to achieve with the prescriptive approach of pure Scrum. We solve our own problems by trying stuff, keeping and tuning what works and discarding what does not. This means that we naturally over time evolve away from any one pure method to an overall approach that we have validated works for Equinox IT and our clients and our combined circumstances and needs. ​

​Working on multiple agile projects and swarming tasks​
WorkingonMultipleAgileProjects.jpgDuring our webinar last week Learning the hard parts of agile software development​, we were asked a number of questions. Two of these are included below with responses:

How do we engage team members to swarm tasks on agile projects?
This can be tricky when people have a particular specialty and identify themselves in that role, and they are required to swarm on another activity which is outside of their core function. Take a developer for example, who may be required to test if a testing activity requires swarming.

What we find is that often project teams have some members who are interested in many aspects of the software development and are naturally inclined to swarm tasks outside of their specialty. These people make great exemplars of the benefits of cross-functional teams and this can be highlighted to the wider team. During stand-up meetings, or walking the Kanban board, the benefits of swarming and the contribution of people who do it well, can be demonstrated and the results speak for themselves when blocks that have been inhibiting the flow of work are cleared via a swarming approach.

It is a sensitive topic to work through, and you shouldn’t force it, but more show the benefit of swarming for the process that you are following and the project as a whole.

Can people effectively work on multiple agile projects concurrently?
Scrum projects have a ScrumMaster, who may be a floating resource across multiple projects. But following Scrum the development team (core developers, testers etc) generally are expected to stay on one project. If you have all members of the team spread across multiple projects then this can be challenging.

One problem is the task switching costs of people moving from one project to another. This creates significant churn and waste which adds up across the project team as a whole and becomes a big overhead.

Another problem, again using the example of Scrum, is looking ahead and planning the work that will be delivered in a sprint and being able to commit to that when resourcing is variable. If the whole team is working on multiple projects with variable allocations and unknown availability, then realistic sprint planning cannot happen. This makes running agile projects well very tricky.

While it may be attractive to spread resources, we believe that it is not that compatible with lean and agile approaches, and raises warning signs relating to the potential for waste and increased costs.

​What is the better method – Kanban or Scrum?​
Whatisbetterkanbanscrum.jpgWe were recently asked this question by a participant on the Learning the hard parts of agile software development webinar. There is no right answer to this question as it is dependent on the team dynamic that you have and the projects that you are working on. Kanban and Scrum are actually tackling quite different problems.

Scrum is more around the team creation and how you approach work. Scrum involves chunking work out into sprints between one and four weeks long, working through them iteratively, and getting a shippable product at the end.

Kanban the method relates to the concept of a continuous flow of work to deliver constant value, which contrasts to Scrum which delivers chunks of work in sprints. As such, Kanban is similar to Scrum but with an infinite sprint length. Many people see Kanban as the Kanban board, which is just one part of the method. The board is about putting a visualisation on your current process and using it to check and analyse how your process is going, to identify pain points.

Depending on the project you are working on Kanban or Scrum may be more suitable. If you are working on a project with larger time frames, say six to eight months and you expect it to deliver at that point, then Kanban may be a better choice. If you need to deliver every couple of weeks, then the sprint nature of Scrum may be more suitable.

Scrum is a larger change activity for your team than Kanban and this may also be a consideration when adopting an agile approach. The team will need to become familiar with a completely new approach to working - Scrum, then use it well enough to deliver project results. Kanban, on the other hand, you can use today, with your existing approach with no further change.

Note also that Kanban and Scrum can work in tandem, enhancing the effectiveness of each other and this may be a topic we can explore in a future blog post.

Further ideas on Kanban and Scrum are also explained in our blog post Can you apply Lean principles to Scrum?​

‘Learning is king’ for agile software development projects
AgileSoftwareDevelopmentInformalMeeting.jpgDelivering excellent business results in a world of accelerating change requires smart people and teams who adapt and continuously improve. In this world ‘learning’ becomes king. Individuals and teams who/that are the best at ‘learning’ will be the most successful today and into the future.

Last week I facilitated a webinar entitled ‘Learning the hard parts of agile software development’ with three members of Equinox IT’s software development teams – Deane Sloan (Software Development Director), Ben Hughes (Systems Analyst) and Hana Pearson-Coats (Systems Analyst). Our software development teams have achieved excellent results from learning, adopting and applying agile and lean software development approaches.

61% of us learn agile best by doing
By learning I am talking very broadly, certainly much broader than attendance on a formal training course. The 70:20:10 model of learning references how 70 percent of learning occurs doing the work, 20 percent of learning is from others and only 10% of learning is from formal training courses.

During the webinar we polled participants on which approach they found ‘most’ useful to learn how to make agile work in practice. Fairly consistent with the 70:20:10 model our results showed that:
  • 61% of responders selected ‘learning by doing by working on agile projects'
  • 25% selected ‘shared learning from coaches, practitioners, managers and teams’
  • 7% selected ‘thought-leader content (books, blogs, podcasts, videos etc)’
  • 7% selected ‘formal training courses and conferences’

This is also consistent with what we see in the market and with our clients. We have found that learning agile and lean software development has many layers. Attending a one or two-day course or getting a Scrum Certification is important to understand the principles and an overview of practices. But this is really just the top layer of learning. Much harder is the learning required to make agile work in practice, the learning required to embed the changes for the long term, the learning required to engage with the business in a different way, the learning required to persevere in the face of resistance, and the learning required to foster a climate of continuous improvement. This hard learning doesn't occur in a classroom environment, but by experimenting, doing and working with those who have done it before.

Our tips for learning the hard parts of agile software development
During the webinar our team members provided a number of tips for learning the hard parts of agile software development. You can see the full set of advice by watching the Learning the hard parts of agile software development webinar. I summarise a few of the ideas discussed during the webinar here:
  • Context is really important – while the formal training component may only be 10% of the learning journey, it is still very important to learn the terminology, concepts and mindset.
  • Allow time to learn and acknowledge that agile and lean approaches will not be highly productive initially while the team is still learning.
  • Work with people who have successfully used agile and lean approaches before, stick to them, do what they are doing. If something is hard, keep on doing it until you get good at it.
  • Get people new to agile working on small tasks where they can start contributing in an environment where it is safe for them to learn. These team members can then be ratcheted up onto more comprehensive tasks from there.
  • Use facilities, such as Kanban boards, to visualise the flow of work so that the approach the team is following is visible, accessible and can be understood and learned.
  • Do your own research and take an experimental and iterative approach. By doing this you solve your own problems by learning what works and what does not, and can then apply this learning to do more of what works and less of what does not.
  • Be conscious of Lewin’s heuristic ‘behaviour is a function of people and their environment’. Learning can often best be enabled not by changing the people, but by changing the environment (co-location, cross-functional teams, embedding coaches in the team and so on).

For us learning has been fundamental to our successful adoption of agile and lean software development approaches. Even though we now are mature in our use of agile and lean, learning still plays a vital role as we seek to continuously improve and as we bring on new members to the team. In the rapidly changing world that we live in I truly believe that individuals and teams who are the best at learning will be the most successful. If learning is king then we all need to get better at learning and hopefully this post has provided some useful pointers to help you along the way.

5 models to help your New Zealand organisation become a digital superstar

In a rapidly changing and increasingly digital world you and your organisation need models and frameworks to help you succeed.

Equinox IT is the only New Zealand-owned IT consultancy that sponsors the MIT Sloan Center for Information Systems Research (CISR). In June I had the good fortune to represent Equinox IT at the CISR summer session in Boston, USA. The summer session had the theme of ‘Generating Business Value from Digitization’. During the session I heard the latest MIT CISR industry-based research findings from leading IT thinkers such as Peter Weill, Jeanne Ross and Erik Brynjolfsson. Topics covered included total digitisation, the future of IT, business architecture, big data, business analytics and the relationship between business and IT.

In this post I summarise 5 key MIT CISR models that were presented at the session that I believe are highly relevant to New Zealand organisations looking to successfully operate in today’s digital economy. Digitalisation, from an IT perspective, refers to the creation of new resources and enriching traditional resources, making these available digitally to invited audiences.

1. Architectural maturity
MIT CISR Architectural Maturity modelTo operate successfully you need a digitised platform that fits your organisation. The architectural maturity model is based on four stages of development: business silos, standardised technology, optimised core and business modularity. In ‘business silos’, the organisational focus is on point or localised solutions that offer immediate business opportunity. ‘Standardised technology’, as its name implies, standardises IT across the organisation to reduce cost and risk. ‘Optimised core’ uses an integrated platform across the organisation to support enterprise wide priorities. ‘Business maturity’ optimises the digitised platform to achieve operational and strategic excellence across the organisation.

The scope of change that delivers business value for your organisation will depend on where you are in your architectural maturity journey.

2. Operating model
MIT CISR Operating ModelUnderstanding your operating model will help you identify the kind of organisational change that will deliver value, and the digital infrastructure needed to support that change. The operating model is determined by assessing the organisational levels of business process integration, and business process standardisation.

A ‘Diversified’ operating model has low integration and low standardisation, such as the independent business units operating within organisations like General Electric. A ‘Replication’ operating model has low integration with high standardisation, such as McDonalds family restaurants. A ‘Co-ordination’ operating model has high integration with low standardisation, such as banks, where credit cards may operate differently from retail banking, but they tightly share information. A ‘Unification’ operating model has high integration and high standardisation, such as international parcel delivery, where standard approaches and shared information is fundamental to getting the item across the globe.

No one operating model is ‘better’ than another, the way the business operates needs to work for your organisation. Understanding your operating model is important to help gauge what kind of change will add value, and what kind of digital infrastructure you will need to support that change, now and in the future.

3. Complexity
MIT CISR Complexity ModelComplexity can be broken down into two forms: How complex are the processes you use and how complex are the products and services you offer. In general, process complexity can reduce value, whereas product complexity can add value.

Understanding your complexity will help you increase the benefits that your products or services add to customers and minimise the bad customer experience of dealing with your organisation because the process is too hard. Digitising your organisation can facilitate both of these areas, offering options to enhance your products and services and streamlining processes.

4. IT value cycle
MIT CISR IT Value Cycle ModelTo deliver maximum value in a digital world, you need to understand the IT value cycle. MIT research shows that getting more business value requires a change to the IT value cycle, extending standard commit, build and run steps to also include an exploit step to gain more value. In this context, exploiting can be thought of as optimising, to gain maximum value from your digitised platform.

In our rapidly accelerating world, the cycle of change is becoming shorter and your organisation needs to both commit to the right change, and operate and exploit what you have today for greater value tomorrow.

5. Value from data
MIT CISR Winning the Data Race ModelGetting value from data within a digital world can improve decision making to build business capabilities and business intelligence within operational decision making.

It is important to understand that gaining value from data requires focus on purpose, analysing data, generating insight, acting on insight and making sure that data provides value.

Summary
Joining all of these models together – if you profile your organisation (or business area) using the first three models:

  • architectural maturity
  • operating model(s)
  • complexity

Pulling together the 5 models to help New Zealand organisations become a digital superstar...then you can do a better job of understanding what change you should commit to for maximum future benefit. You can also identify how you can operate and moving through to the last two models exploit what you have to get maximum value, and leverage data to inform your operational and strategic decision making.

Successful change is change that works with the way your organisation operates, and supports the strategic direction of the organisation. Applying these models can help you to identify and deliver successful change within the organisation you have now, and build the organisation you want.

All five of these models come from the great research performed by the MIT CISR, and you can find out more details about them on the MIT CISR website. In my 'Creating organisational success in a digitised world’ webinar I also discussed the models further and brought all 5 together into a framework for thinking about change, digitisation and value within your organisation. Becoming a digital superstar is about understanding where your business resides in each of these models and using IT as an asset to maximise your business value through digitalisation.

Overcoming the challenges to successful cloud adoption in NZ
Overcoming challenges to successful cloud adoption in New ZealandIn this post I put forward ideas to help your organisation mature its approach to cloud adoption. The post covers some of the key problems that New Zealand organisations face when adopting cloud services, and five pragmatic tips to help you be more successful. If you want more detail, I also elaborate on this topic in my recorded webinar Moving your organisation to the cloud.

Cloud adoption is harder than you think

Cloud services have many benefits for organisations, and based on overseas trends we expect to see the adoption of cloud services accelerate in New Zealand. Wherever your organisation is today, effective cloud adoption and management will increasingly become pivotal to your future success.

Unfortunately many organisations underestimate the effort required for secure and effective cloud adoption. Organisations may also face resistance to change from roles impacted by new ways of working. Furthermore, many IT teams are being side-lined as business units procure services they need directly, without the perceived IT bureaucracy.

It is clear that new skills are required as IT’s role transitions from service delivery to service brokering. As cloud becomes more predominant, we need to start preparing ourselves to better leverage the full benefits that this powerful set of services have to offer.

Top 5 problems and solutions New Zealand organisations face when adopting cloud

Problem 1: Poor understanding of enterprise data – information is one of your most important assets, but how well do you know your information? Organisations who do not understand the nature and value of their information will find it near impossible to determine the best way to manage this information in the cloud.

Solution: Classify and categorise your data – you need to baseline an understanding of the information within your organisation. This means uncovering what data is used, and how it is used by systems, processes and people. Analysing your information in this way will allow you to categorise your data and form a view on the appropriate level of information security.

Problem 2: Uncertain data sovereignty rules – most cloud services are not located in New Zealand and as a result there is uncertainty around the legal requirements and implications of storing data with offshore cloud service providers. This has been further complicated by the US National Security Agency and UK Government Communications Headquarters accessing data that is stored with cloud providers who host in their respective countries.

Solution: Seek legal counsel for offshore services – legal advice will help you navigate the tricky area of data sovereignty, particularly if your information relates to government, financial or sensitive topics. It should also give you a better handle on whether your information is likely to attract attention from host nation intelligence agencies, and the implications of this.

Problem 3: Inadequate guidance and advice – adopting cloud services can be an unchartered territory for many organisations, and cloud vendor assistance can be biased towards their solution rather than the broader considerations and implications. There are risks with cloud services, and the process of adoption absolutely requires an ‘eyes open’ approach.

Solution: Understand what cloud adoption entails – building a repeatable process and check list for adopting cloud will be valuable, and will help you identify and mitigate important risks associated with cloud services. There are various resources that may help with this, including the New Zealand Cloud Computing Code of Practice, the ENISA Cloud Computing Information Assurance Framework, the CSA STAR Assessment Framework and the New Zealand Government Cloud Computing Considerations paper.

Problem 4: Difficulty applying security controls – everyone wants cloud services to be secure, but what are the appropriate security controls for your information and your particular cloud service implementation and circumstances?

Solution: Take a risk-based approach to information security – since you can’t apply every information security control to cloud services, I recommend taking a risk-based approach. This will allow you to assess the actual risks within the context of the cloud service and the needs of your organisation, helping you identify and implement the most appropriate security controls.

Problem 5: Outdated procurement and governance – procurement approaches that are centred around large up-front spend, predictable support and maintenance costs, do not translate well to cloud adoption, where costs are based on service provision.

Solution: Update your procurement processes – perform a gap analysis between your existing procurement and governance processes and what is required for effective cloud service procurement. This should allow you to identify the changes necessary to update your procurement processes to suit your organisation’s needs today.

During my Moving your organisation to the cloud webinar we polled the New Zealand attendees to identify which of these 5 problems was most significant for them. As you can see below the results were quite evenly spread, with security and data being the leading considerations:

Poor understanding of enterprise data: 24%
Uncertain data sovereignty rules: 21%
Inadequate guidance and advice: 19%
Difficulty applying security controls: 30%
Outdated procurement and governance: 6%

With cloud adoption in New Zealand set to accelerate, your organisation needs to prepare itself to become better at adopting and managing cloud services. Cloud service adoption is not as simple as cloud vendors will have you believe and there are many tricky ‘got-yas’ once you look beyond the vendor marketing. This post is a good start to prepare yourself for successful cloud adoption. The information presented here is also covered in more detail in my recorded webinar Moving your organisation to the cloud. If you need specific advice, you can always get hold of me by contacting Equinox IT.

Equinox IT was instrumental in setting up the New Zealand Cloud Computing Code of Practice, along with the IITP and other organisations such as Xero. We are now a signatory to the CloudCode.

Integrating business intelligence tools into your application
I’ve blogged several times over the years on various aspects of how we use Business Intelligence tools to visualise the mountains of data we accumulate in the course of our Performance Intelligence practice assignments. Even the practice name of “Performance Intelligence” reflects the vital role that such tools and techniques play in deriving insights from all of that data to allow us to get to the bottom of the really hard system performance problems.

Our data visualisation tool of choice is Tableau, because it connects to pretty much any type of data, offers a very wide range of visualisation types and can handle huge volumes of data remarkably quickly when used well. But up until now we have always treated Tableau as a standalone tool sitting alongside whichever performance testing or metrics collections tools we are using on a performance assignment. That works fine – but it does mean that the analysis and visualisation doesn’t form an integral part of our workflow in these other tools. There are lots of opportunities to streamline the workflow, allowing interactive exploration of test results data – drilling down from high-level summaries showing the impact to low-level detail giving strong clues about the cause of issues. If only we could carry context from the performance testing tool to the visualisation tool.

Tableau business intelligence tool integrated with Visual StudioWe have recently been working to address that, making use of an integration API which Tableau introduced with their last major release. First cab off the rank for us was integrating the visualisations into the Microsoft Visual Studio development environment, since that provides one of the performance testing tools which we use extensively in our practice, and the Microsoft Visual Studio environment offers the extensibility points necessary to achieve tight integration.

But whilst the integration is conceptually straightforward - we just want the visualisations to form a seamless part of the experience of using the tool and to know the context (what is the latest test run, for example), actually making it work seamlessly and perform well required careful design and significant software development skills.

The Tableau API uses an asynchronous programming model - JavaScript Promises (so called because when you call an asynchronous method the response you get back is not the answer you are after but a “promise” to return it in due course). Using this asynchronous model allows the client-side behaviour to remain responsive whilst potentially long-running requests involving millions of rows of data are handled on the server. Putting a simplistic proof-of-concept together was within my powers, but actually achieving tight integration in a robust and well performing way definitely needed the professionals. So I’m very glad that we had the services of our Business Application and Product Development business available to do the integration work.

We’re very pleased with the end result, and the folk at Tableau liked it enough to invite me to talk about it at their annual user conference in Seattle – which this year will have a staggering 5,000 attendees. As part of my conference session I put together a simple demonstration to show how the interactions work. It is a simple standalone web page with an embedded Tableau visualisation object in it – showing how the user can interact with the Tableau visualisation both from controls on the hosting web page and from within the Tableau object itself.

See the integrated Tableau wave pendulum demonstration

Image of YouTube video from San Diego State University showing a wave pendulum effectThe demo is an animated emulation of a video made by the San Diego State University Physics department showing a cool set of pendulums – the link to the video is in the demo page. It has a couple of controls on the hosting page (a play/pause) button to start and stop the animation and a field to enter the time delay between refreshes. You can also interact with the visualisation itself (when it is paused) by changing the Time Parameter – which determines how far through the cycle the emulation is.

You can download the source for the demonstration and also the source of the Tableau visualisation itself from the Tableau Public website using the links in the demonstration page, if you want to look under the covers to see how it all works.

Wave pendulum visualised using Tableau, integrated into an pageNote that whilst the example is a bit of fun, I absolutely don’t advocate trying to animate complex visualisations at a high refresh rate like this. But there may be contexts in which this technique could be useful.

Whilst the demonstration itself is very simple, the possibilities that are opened up by interacting with the visualisation from an external application or web portal to pass in external context are enormous.

Change or die - the changing role of IT departments

Change or die- the changing role of IT departmentsThe IT industry is undergoing a seismic shift. Unlike previous technology revolutions, the changes to the way services are delivered to organisations and end users is forcing dramatic changes to the way organisations view technology, and how they are structured to deliver IT services. Change is happening, and how organisations choose to react to that change will determine their future relevance in the marketplace. What is driving this change, and how can organisations, specifically IT departments adapt and thrive?

I was watching an article on the news the other night that talked about IP-based messaging platforms (like iMessage) replacing trusty old SMS. The recent acquisition of WhatsApp by Facebook for an eye-watering $16 billion USD shows just how much belief major industry players have in growth opportunities around this segment of the market, at the expense of ‘legacy’ telecommunications providers.

In the same way that telcos are seeing their role being relegated to a commodity provider of a ‘dumb pipe’ for home and mobile broadband, those in the traditional IT infrastructure space are also at risk of having their lunch eaten by external competitors who can now deliver what was traditionally a complex service as an on-demand utility.  Cloud infrastructure is transforming delivery and operation of servers, storage and network devices into ‘dumb infrastructure’ commodity services. 

Today, few IT departments have the depth and breadth to design, develop, test and operate an entire suite of enterprise applications. The rise of ‘off the shelf’ enterprise software over the last 30 years demonstrates the validity of a model where much of the heavy lifting is provided by an external vendor when in house-capability does not exist, or an organisation chooses to focus its limited resources elsewhere. In recent years we have seen this approach extend further, to a full Software as a Service (SaaS) delivery model where all aspects of the software development lifecycle are managed by the service provider.

The progression of software delivery towards SaaS points to the future of IT infrastructure within an IT department. Rather than build and operate infrastructure using ‘off the shelf’ servers, storage, networking and operating system components, a range of Infrastructure as a Service (IaaS) offerings are available on-demand. IaaS increases the responsiveness of technology to business needs, provides cost reduction opportunities, and delivers a better quality service while shielding customers from the complexities of service design, delivery and operation.

The benefits of IaaS are often the same attributes used by IT departments to justify their existence to the business. If one of the core capabilities of IT is no longer perceived to be of value, how can it continue to remain relevant to the business? Transforming IT from its current role as a service provider to one of a service broker is one such way to retain relevance. While some technical skills will remain relevant, especially those related to security, integration and data management, others such as system design, delivery and operation will recede in importance. The real shift however is moving away from a focus on technology towards a consultative model where IT works as part of the organisation to deliver business outcomes. An increase in skills relating to business processes, requirements analysis, the management of commercial agreements, and most importantly, the successful management of the intersections between business and technology will be required by tomorrow’s organisations.

Change of such a scale is not easy, and requires understanding, planning and commitment at the very highest levels of an organisation. Those that are able to successfully make the transition will reap the benefits of utility computing and flourish in tomorrow’s environment. Those that hold tightly to old operating models may find themselves like many of today's telcos - a service provider without a customer.

Drowning in documentation

At first glance, documentation may not be the sexiest topic for any IT professional, however it is often the standard by which our efforts are judged, especially by those that encounter our work after we have left the organisation. Few things in the life of an IT professional can be as frustrating as attempting to understand or support an IT system without having the required information available.

The standards of documentation I’ve encountered over the years vary wildly, and sadly many represent an afterthought of an otherwise talented developer, analyst, or architect. A solution is immediately more accessible and understandable when well-written documentation is incorporated as part of the solution. This in turn increases the value of both the service, and also of the writer. Creating well-written documentation should be a foundation skill of any architect, systems engineer or software developer.

I've encountered a number of projects and clients with differing expectations around how information should be captured. These range from engagements where the majority of time was spent writing documents to adhere to strict standards, through to projects where documentation is almost a foreign concept, and critical knowledge about systems is trapped in the minds of people who one day will move on, usually taking that knowledge with them. Even with more projects moving towards agile delivery methodologies, documentation remains an important component. What are some key tips to keep in mind when crafting good technology documentation?

1. Relevance to a wide audience

Can you as an author say with complete confidence that you know everyone who may want to make use of your documentation? If the answer is "no" (which it often is) then cast your net as wide as you possibly can before you start to sacrifice the truly important messages that you wish to convey. A document primarily aimed at a technical audience can with the right approach be just as useful to non-technical readers. In doing so you can not only increase the relevance and value of your documentation but you can also cut down on duplication - "one document to rule them all" is surely better than spending time and effort creating two or three audience-specific documents.

2. Forsake detail for the sake of brevity

Sometimes it can seem like a good idea to exhaustively document every nuance of your solution - you never know when you'll need to refer to it right? Realistically though, just how likely is it that you or another reader will need to know that the SSH service is set to start automatically on boot (which was the default anyway) - Can't they just look up the vendors online documentation for that information?

If you try and document everything it becomes tiresome to capture, almost impossible to maintain, and the messages that truly matter (like the fact that you must allocate at least 20GB of swap disk) get lost in the noise. Focus your documentation on the non-default decisions of your solution. Presumably each of these decision points is in some way justifiable, so provide the reason ‘why’ they were changed as well as ‘what’ needs to be changed. For those circumstances where it is useful to have a comprehensive configuration options documented, consider an appendix, or even better, make them part of build or deployment scripts so that they are truly reusable.

3. Standing the test of time

Let's be honest - most systems outlive their intended lifespan by a number of years. Dive into design and operational documentation for an enterprise application and you'll encounter a lot of information that is past its use-by date. Normally this relates to the attributes such as server names, operating system versions and such that at first glance seem to be reasonably static, but actually have a fairly highly chance of changing over a long period as components are upgraded and dead servers are replaced (virtualisation and IaaS complicates this even further).

In theory, documents should be updated when changes occur but in reality this rarely happens. However, most organisations today implement some kind of configuration management database (CMDB) to track IT assets. Linking to a service's CMDB entry in the documentation is a better way of providing up-to-date information about changeable infrastructure elements.

Documenting organisational structures, roles and personnel can be just as risky. Organisations change over time, as do the people that perform specific functions. When the need arises to capture this information, consider the role as well as the person, and to ensure longevity make sure you provide a description of the role. This way when "Systems Administrator" gets renamed to "Technology Service Availability Manager" after a particularly energetic round of corporate re-branding you can still track down the right person.

4. First impressions count

Nobody likes an ugly document.  Bad fonts and formatting issues can turn people off just by glancing through the first few pages. Most people learn through visual stimulation, so support your text with diagrams where appropriate. Take a look at professional websites and published documentation for pointers on how to structure a page in such a way that it is easy on the eyes and draws the reader in.

5. Use everyday language

This point has been hammered home so many times over the years, but it seems the powers of business pseudo-speak are strong. Throw out jargon like "synergy", "moving forward" and "leverage" like old ham. Once ingrained, this habit is incredibly hard to break and even this author falls back into referring to "deliverables" and "low-hanging fruit" without thinking.

The problem with this type of language is the emptiness of meaning. Jargon stands in the way of proper expression, and in the worst case, can be used to intentionally obscure facts and information. Technology is precise, unambiguous, and definitive. All things that jargon isn't.

Conclusion

We in the technology sector more often than not work in an abstract world. You can't hold software in your hand. Nowadays we rarely have the opportunity to even touch a server, storage or network component. Documentation is the bridge between the abstract and the real world. Rather than treat documentation as an afterthought, we should write with pride, and use it as an opportunity to increase the value of the solution and a chance to close the gap between technology and people.

The top 5 cloud integration challenges that NZ organisations face and how architects can help solve them
Cloud integration problems and solutionsRapid adoption of cloud technology worldwide has meant that many New Zealand organisations are already testing the water by shifting non-critical workloads to the cloud. However, when business-wide applications move into the cloud, they need to integrate not only with on-premise systems, but also other cloud services.

Our experience with New Zealand businesses has shown that integration is a key concern for those organisations considering cloud service migrations. This post explores the 5 top cloud integration problems and how IT Architects can address these when considering the implementation of cloud services.

Top 5 cloud integration problems

1. Fewer Integration Options
Often the options for integrating with a cloud service are dictated by the cloud service provider. While traditional batch file transfers may be supported, we find in most cases cloud service providers rely on APIs of various flavours. For organisations without a Service Oriented Architecture (SOA) capability or the ability to provide message translation services, successful cloud integration will require significant investment in your teams cloud architecture skills and experience.

2. Poor understanding of data flows
We find that organisations often do not have a clear understanding of the nature and extent of information that will be stored in their cloud service. Not only do cloud services hold your information outside of your organisation, but many services also require access to your on-premise systems, potentially exposing you to a range of security risks.

3. Ad hoc approaches to integration
Many organisations approach cloud integration on a project-by-project basis. However, as cloud adoption increases across the enterprise, this ad hoc approach to integration increases architectural complexity and overheads for the entire organisation that becomes increasingly hard to maintain and enhance. Project based approaches to cloud integration will result in ongoing costs remaining high, eroding the benefits cloud services can deliver.

4. Lack of suitable tools
The capability to integrate systems using SOA or custom APIs is something that many New Zealand organisations still lack. Many older on-premise applications have APIs that were developed prior to the emergence of cloud services and may be incompatible with newer, cloud-centric standards. In addition, some internal systems were not designed with any integration in mind, making successful cloud integration even more challenging.

5. Latency and performance
Due to New Zealand’s geographic location, cloud service providers are usually based halfway around the world from their kiwi clients. This raises concern around the ability of the provider to support the needs of their clients, such as reliable delivery of synchronous, near real-time communication.

What can New Zealand cloud architects do to mitigate these problems?
The following 5 approaches can be used to overcome some of the cloud integration problems your organisation may be facing:

1. Create an integration strategy
An integration strategy should present a structure of how your organisation will approach the integration of cloud services. It’s vital you apply your strategy at an enterprise level to ensure all areas of the business are accounted for. Practical guidelines directing standards and protocols for data transfer that are specific to your business should be included, with close ties to any existing identity, data classification, and information security policies. Standardised integration patterns should also be developed to enable a faster and smoother design and delivery of the solution.

2. Establish a shared integration platform
This demands a move away from integrating on a per-project basis, towards establishing a shared set of integration tools. Functions such as message, routing, translation and transformation are required to move data between systems that may not speak the same language. This means SOA gateways and message busses shift from “nice to have” status to key components of the IT service portfolio.

3. Balance flexibility with complexity
A good strategy should provide solid guidance but allow for flexibility to meet the needs of specific projects and systems. One of the key objectives of strategic integration is cost reduction, so ensure you don’t erode this benefit by defining unnecessary levels of detail and complexity in your integration architecture.

4. Understand your data
A good integration strategy leverages the knowledge an organisation has of its information. Make sure that your organisation comprehends the importance of its information, regardless of whether it is stored on-premise, in cloud services, or transferred between systems. This will enable the appropriate levels of control and visibility to be put in place, reducing threats to information security in a manner that fits the context and objectives of the business.

5. Don’t forget identity
Many organisations focus on data integration whilst forgetting the importance of identity integration. The result is identity fragmentation across your services, with users having to juggle multiple usernames and passwords. Through directory federation or identity replication, organisations can retain control over who accesses their cloud services, and provide a better user experience.

The uptake of cloud services is set to accelerate in New Zealand over the coming years. Cloud integration will continue to slow cloud adoption and the realisation of cloud benefits until we start taking a more strategic and enterprise-wide approach. Creating an integration strategy and establishing a shared platform that is right for your organisation will help you efficiently and effectively transition to cloud while maintaining the necessary control over your organisation's critical information.

4 steps to becoming a New Zealand IT hero

4 steps to becoming a New Zealand IT heroMany New Zealand IT professionals fear moving out of their comfort zone. However, having a successful IT career is about more than ticking boxes at your annual performance review. It’s about taking risks, grabbing opportunities to grow and surrounding yourself with a great team from which you can learn and develop.

So how do you take the initial steps to commence the journey to accelerate your IT career? This post identifies the four key steps all IT heroes setting out on their journey will experience along the way. Don’t worry – every hero reaps reward in the end.

1. Yearn for something more

The first thing you need to identify is what motivates you. This will help you to understand how to accelerate your IT career in the right direction. It might come as a surprise, but often we are not as motivated by money and status, as we are by the intrinsic motivators of Autonomy, Mastery and Purpose.

  • Autonomy is the desire to be self-directed, to manage your own time. If you are new to your role or new to your organisation, this most likely applies to you. You desire to move from ‘beginner’ status to ‘intermediate’.
  • Mastery is the urge to make progress and get better at something that matters. If mastery motivates you, you might think of yourself as a perfectionist. You might want to craft beautiful code or design elegantly simple architecture.
  • Purpose is the yearning to do what we do in the service of something larger than ourselves. If purpose is what motivates you, you will be motivated to make the world a better place.

Once you have identified your motivation you can begin your journey pointing in the right direction. However, every hero needs a sidekick or two to guide them along the way.

2. Surround yourself with support

Start looking for people to fill the roles that can drive your career forward.

Ideal mentors are people who you respect and admire because of the achievements they’ve had in their career. Selecting a mentor that has successfully been through the journey you are about to take makes sense. A mentor doesn’t need to be someone that works in the same industry as you, as they should be guiding you around personal development and how that can shape your professional career, rather than advancing your technical skills. Think of the relationship as helping to establish your personal brand.

In addition you need to identify a performance coach. Unlike a mentor, a coach is task-oriented so the focus of this relationship is on concrete issues like closing a skill gap. This means coaching is a short-term relationship as it only lasts as long as that gap is present. Your line manager, your peers, books & webinars and classroom training all could be great choices to fill the role of performance coach on your journey.

Industry networks are highly valuable resources when looking to accelerate your career. Mixing with people that share the same passion for the industry you operate in can open doors to mentorships, coaches, training and career opportunities. Joining an industry body in your chosen field should be top of the list in order to expose yourself to new experiences and make valuable contacts.

Lastly, as you journey into the unknown, you will inevitably pick up more skills from your experiences. Setting a benchmark of your current capabilities means you will have a better sense of your progress. Having a clear picture of your current skill set will also help you identify the capabilities you want to grow. Don’t be a jack of all trades – aim to be a master of some.

3. Commit to change – navigate through trials to triumphs

Stepping out of your comfort zone will be tough. You will experience setbacks along the way, so it is useful to try and identify what challenges you will face, so you can best prepare for them and not let them throw you off course.

  • The reality is that if you want to accelerate your career, you have to accept that a level of sacrifice is required in terms of your personal time and monetary investment.
  • Failure is inevitable. If you want your career to be on a different trajectory than it is now, you are going to have to try new things and you won’t get them right first time. When you learn something new, and practice applying it, your performance will get worse before it gets better.
  • Being knocked back from an opportunity you felt should have been yours (a new project, a new job) will dent your self-confidence. The best solution is to learn from the experience. What could you do better next time? This is also a good time to call on your mentor.

Remember, to guide your through this often uncomfortable process is your mentor, your coach, and the industry network you have built. Progressing through these challenges you will develop a clearer vision for your future, and you’ll know what gets you out of bed in the morning. Most of all, having fought through your trials and successfully accelerated your IT career, you’ll be more confident in your abilities to continue to grow and change.

4. Embrace your new hero status

On completing your journey it is worth taking time to reflect and examine the experiences gained. Success achieved on the hero’s quest can be life-changing, for you and often for many others. Knowledge picked up along the way instils higher engagement, greater job satisfaction, stability and higher performance, resulting in an enriched work life.

Reflecting on the initial motivations that guided you, you will discover that you have earned greater autonomy, mastered a new skill or domain or will be doing more purposeful work. You will now be in a good position to mentor others on their journey and after a rest, you might even be ready to head off again!

5 ways to be a better agile business analyst in New Zealand
Martin White, agile business analysis New ZealandDo you want to deliver better results as an agile business analyst?

Instead of trying to predict the future when planning delivery of business requirements, agile business analysts respond to change as it happens, resulting in reduced time wastage and a more collaborative team work environment.

Applying the agile philosophy does not necessarily require changing the activities you already perform. You can enhance your agility significantly simply by restructuring the timing and sequencing of these activities.

As Equinox IT’s Software Development Manager I am responsible for a number of agile business analysts. Based on our experience of delivering numerous agile projects in New Zealand I share in this post the five ways I’ve seen agile business analysts deliver better results. These approaches enable business analysts to focus their team on achieving business objectives and add considerable business value.

1) Create the vision and context
As the business analyst you are the conduit between the business and your team, so it is important that you ensure your team is focused in the right direction and working towards the defined business objective.

Development teams are often disconnected from the business and find themselves working on small pieces of specification without understanding how their work fits into the project in totality. Regularly focusing the team on the overarching business objective “the big picture” will provide important context, facilitate alignment and enable each member to understand the value of their contribution.

As the business analyst you can increase the focus on business value. This is important because most organisations have management structures that focus on managing people, rather than value.

2) Be part of the team
New Zealand business analysts are often located separately from the development team. Physically moving into the team helps to facilitate cross communication, encouraging discussion of work in progress and keeping the business analyst better informed.

Business analysts often run ahead of the development team. But in an agile environment you should aim to minimise this gap in order to provide opportunities to work collaboratively. This may mean understanding the high-level stories and acceptance criteria ahead of the sprint, but the elaboration of these with the business and the development team happens during the sprint. When everyone is actively involved in the progress of the software solution this results in less room for error and mis-communication.

3) Accommodate Change
One of the fundamental truths of being agile is the ability to accommodate change. This starts with refraining from locking down details until the latest possible moment. Over the course of a project business objectives can change and priorities may shift. Adopting a more fluid agile approach gives you the ability to accommodate change as it arises along the way.

Central to this is the importance of encouraging client involvement by providing frequent opportunities for feedback. The more actively involved the client is the sooner you will be aware of changes or amendments required, thereby minimising the need to re-do work.

Remember to ensure you have a controlled ‘trackable’ feedback system in place. Increased client feedback can result in many small tweaks and changes filtering through to the team. These need to be managed and followed through effectively. Commonly this is managed through backlogs and visual workflow tools such as Kanban boards.

4) Specify acceptance tests for requirements
Your effectiveness as a business analyst is ultimately measured by how well the software delivers the required business value.

Often in New Zealand business analysts get involved in acceptance testing at the end of the software development process, which is too late. If you can only confirm that your software has delivered business value at the end of the project, you may discover that there is a good deal of rework required and a lot of wasted resource and effort.

In our experience, much greater business value is delivered by combining detailed requirements and acceptance test specifications as one activity. This is further enhanced by writing test specifications in such a way that the testing of them can be automated using an agile approach called acceptance test driven development (ATDD). Using these approaches enables software to be validated immediately as each requirement is developed, minimise waste and rework and maximising business value.

5) Stop starting and start finishing
In our experience New Zealand IT professionals all want to do the best job that they can. The problem is that many teams have a tendency to keep going, gold plating and polishing until something is perfect. But what if this is beyond the level of quality that the customer needs? Then we have wasted time and resources to add no further business value. As a business analyst on an agile software development project you need to provide a very clear definition of what done means in terms of both functionality and quality for each story, and once it is met the team must stop working on it.

We have found that many New Zealand software development teams find it difficult to successfully adopt agile. Business analysts play an important role in agile projects by creating the vision and context, by being part of the team, by helping the team accommodate change, by testing early that business value is being created and by making it very clear when a requirement is met. Do these things well and you should find that you whole team starts getting much better at delivering success agile software development projects.


The seven habits of highly effective agile analysts

Agile Business Analysis Q & A
On Wednesday 30 April 2014 I delivered a webinar entitled The seven habits of highly effective agile analysts. We had great attendance on the webinar with many questions asked. We had so many questions relating to agile software development and agile business analysis that we could not answer them all during the webinar and so we promised to write this blog post to answer the remaining questions.

Where the answers were quite short, we have answered these as part of the post below. Where the answers were long, we have created individual posts for each question and linked through to these from below.


What are the benefits of using Agile? (Sue)

Please see our post What are the key benefits and costs of using Agile approaches to software development?


Any tips to incorporate feedback in a controlled way? (Laura)

Please see our post How can agile business analysts incorporate feedback in a controlled way?


Just software? (Andrew)
which we interpreted as 'Is Scrum only relevant to software development?'

During the webinar we spoke about agile and Scrum in the context of software development. Fair point from Andrew. You absolutely could use Scrum as an agile approach for non-software development projects. Agile methods, such as Scrum are typically about software, but many of the principals and practices could be applied to just about any type of project. Scrum is particularly well suited to other types of projects because it is about organising a team and not about the construction practices. Alternatively, XP is much more about construction practices that are industry specific to software development.


Good change control allows waterfall to constantly change requirements at any phase in a project. Perhaps you have been on bad waterfall projects? (Andrew)
Absolutely waterfall can allow change. I think it just makes it harder. If you have to go through a change control process in order to make a change, then your natural tendency will be to try and avoid that because there is more hassle involved.  If you minimise the level of that hassle, then it becomes less of a big deal absolutely. But usually it is a hassle, especially for projects where there is a contractual relationship. Going through change control tends to imply that you have to spend more money, is often considered a sign of 'bad' behaviour on the part of the stakeholders or business analysts, and is generally seen as a bad thing and to be avoided. 

Agile encourages us to be less specific about the details of the scope of the project, and this is what I was talking about during the webinar when I mentioned deferring detail until the last responsible moment. If you start with less specific requirements (which is what user stories are all about) then in many instances there is no change, it’s just that you are elaborating the detail in the right way, just in time for when it is needed, with the most up-to-date knowledge.


That is why requirements take time to write and trying to do them in the sprint will result in errors? (Andrew)

Please see our post Will analysing complex requirements in short agile sprints result in requirement errors?


The difference between a story and a requirement is the level of formality (Andrew)
And detail. A story is a 'placeholder for a conversation', which is held when the detail is needed for implementation.


The project team I am currently working on has adopted the OpenUP methodology, with four phases being Inception, Elaboration, Construction, Transition. Is this considered Agile on some level? (Sash)
Many years ago Equinox IT used to develop software using the Rational Unified Process (RUP). OpenUP is the open source version of this same approach. RUP and OpenUP are considered to be iterative software development approaches, so typically they should be somewhat more responsive to change and more agile than waterfall. However, standard RUP or OpenUP do still encourage quite a bit of up front planning and elaboration of requirements into detailed use cases early. These approaches also exclude many of the practices that you would see on a typical agile project. Note that Scott Ambler has created the Agile Unified Process (AUP), which is simplified version of RUP and does incorporate agile practices to improve productivity. Exploring in this area may provide some insight into how OpenUP could be run in a more agile manner.


How is this different to a project manager? (Mark)
This refers to my comments during the webinar that the business analyst plays an important role in creating the vision and context. So first thing to say is in Scrum there is no Project Manager role. If you are working in a non-agile environment and you have a project manager then one of the things that role does is maintain the vision and track progress towards it. If you move to a Scrum environment and decide, as many people do, to dispense with the project manager as a role, then who is going to take on the responsibilities for that vision? My view would be that the BA would do it (however, it should be noted that the BA role is also not defined by Scrum). A product owner could be another good role to create the vision and context for the agile development team - I'm not dogmatic about who does it!


Can agile be used if you don't have developers on site, being developed by a vendor? (Michael)

Please see our post Can agile software development be used if you don't have developers on site?


What is the difference between an agile business analyst and an agile product owner? (Matthew)

Please see our post What is the difference between an agile product owner and an agile business analyst?


Aren't the business requirements and specification by example the same? Just setting an acceptance criteria? (Ismath)
No. With specification by example the key words are 'by example'. Acceptance tests are not the same as acceptance criteria. Say we are talking about the salary calculator example I used in the webinar. The acceptance criteria for this feature might include 'Must pay double time for hours worked on Sundays'. An acceptance test for this might be 'Given I have an hourly rate of $20, and in a week I work 30 hours on weekdays and 5 on a Sunday, then my pay for that week will be $800'. Its an actual test, which can be automated, with inputs and resultant outputs that can be verified by the client. There will usually be many acceptance tests for each of the acceptance criteria.


How do you set up an agile infrastructure? What tools do you need to set it up and how do you govern the process? (Ismath)

Please see our post How do you set up an agile software development infrastructure?
  

The seven habits of highly effective agile analysts

May 12
How do you set up an agile software development project infrastructure?
Setting up an agile software development infrastructure will vary depending on the context. By context I mean what type of software it is, what type of team it is, what type of company it is, what’s the culture like, what tools do you have? These things vary from company to company, project to project and situation to situation.

However, there are some things that I would always do to set up an agile infrastructure from scratch regardless of the context:

Visualise a product backlog
Start by knowing what work there is to do and visualise this in the form of a product backlog. This may be as simple as a spreadsheet with a list of items or as complex as a Kanban board where you can visualise the product backlog and the flow of work through the development process.

Set up a planning process
In Scrum at the beginning of every sprint (usually every two weeks) you do sprint planning. Even if you aren't following Scrum, you do need to do regular planning and re-planning. The frequency could be anything from weekly to monthly; you probably don't want to go beyond monthly. This then becomes your planning cadence.

In our experience the sprint or iteration planning is between a one and a four hour period of time when you get the whole team together to look at what things from the product backlog you are going to do in the next sprint or iteration.

Set up a review process
You need to set up a process where you get feedback from your business or your client. It doesn’t necessarily need to be the same cadence or regularity as your planning cycle. In Scrum it is, but it doesn’t have to be. On one of our most recent projects, we had weekly reviews with our client to start with and we found it was too often. We found we weren’t getting enough done in a week to be worth showing the results to our clients. So we changed it to fortnightly. On this project we were doing weekly planning and fortnightly reviews.

Set up a retrospective process
Retrospectives are when the agile software development team looks back on what they did in the last period of work and reflect on whether improvements can be made to the approach. Again the cadence for this doesn’t need to be the same frequency as for your planning or review processes. At Equinox IT we do this monthly for an established team, or more frequently for a new team or a new approach.

Establish a mechanism for tracking progress
Earlier I stated the need to establish a process for sprint or iteration planning. But, how do you know that you are on target to do all that work that you planned for the sprint or iteration? On agile software development projects typically people use a burn down chart to track outstanding work versus time remaining. This allows them to visualise whether the agile team is on track for the sprint or iteration.

Next, consider how you will be able to know you are on track for the overall project, to deliver an application that has all of the features that the customer wants three or six months from now. In other words how do you know you are planning enough work into each iteration or each sprint to meet that longer term deadline? For this you need a more coarse grained burn down chart or equivalent mechanism. If you are estimating your work using story points or any other unit, then you need to track that you are delivering enough of those units in each iteration to be able to meet that longer term deadline.

Start trialling and adding in other agile practices
Once you have the above mechanisms and routines in place, you have a platform to start working in an agile way, but it is not everything. That’s one of the things about Scrum, it only tells you how to organise your teams to do the work or what work to do. It does not actually show you how to do that work.

So agile development practices and XP practices such as test driven development (TDD), acceptance test driven development (ATDD), modular, loosely-couple code design, pair programming and code reviews are not covered within Scrum. These are things that you can pick and choose from.

However, some of them you need to establish from the start as they are difficult to add later. Practices relating to the design of your code or test automation in particular are the hardest to add later. Some teams have a team charter, project charter or a quality management plan that dictates the sort of up front things that the team is going to do. So one of those might be 'we are going to use test driven development and we are going to achieve X% coverage'.  

Having code reviews, pair programming and daily stand ups are things that you could introduce incrementally as you go through. Then you can review the impact of them, whether it was worth it and whether you want to continue with these practices.
