Mapping Agile Architecture

Jason Bloomberg recently published a mind map for Agile Architecture. It’s a nice map that sketches top level thinking and I welcome that. It prompted me to do a drill down.

Mind maps are useful in that they are, by definition free form and intended to support brain storming. The downside is obvious – they are generally inconsistent and cause modelers’ intense frustration! Caveat emptor over, I fully agree with Jason that we need a dual interpretation of Agile  – that is Agile practices and Agile Architecture, and I have written about this on many occasions. Also that the entire motivation is about business agility. On this last point my mind map is clearly a little more technical than Jason’s, and on reflection I think that is because it’s essential to converge the business and technology concerns.

For example, the map suggests a strong capability centric approach to interpret the business morphology. However this is insufficient; the technology must also establish appropriate levels of implementation independence that will facilitate the pluggability of business capabilities. Similarly you might think that considerations regarding the platform and delivery technology (such as MDA/MDD) are irrelevant to business concerns. However the platform and platform delivery technology are potentially massive drivers of rapid iteration and ongoing change, because they encapsulate common application level infrastructure and common services, so understanding the “business” standardization and localization model is crucial to delivering agility through this structure.

Scaling Agile means Scalable Architecture

With the growing popularity of Agile, mainly in applying Scrum for IT development, issues need to be tackled relating to scaling up the development effort. Scrum came to birth in small teams that had a lot of mandate, typically 3 to 10 person teams. Now we see Scrum used for major efforts, involving hundreds of […]

How Do You Measure Up?

One of my life-long idols, Muhammad Ali is quoted as saying, “The man who views the world at 50 the same as he did at 20 has wasted 30 years of his life.” Can you point to a specific situation where you have changed your mind? On the topic of a…

Architect or Coach?

Is it just me, or are others finding the Enterprise Architect role shifting towards ‘Coach/Facilitator’? 
These days I find I’m most attracted to Tweets about workshop facilitation and business analysis techniques rather than anything discussing Enterprise Architecture: frameworks, methods and tools. 
Here’s a few links I’d recommend for those interested in the former.

Towards an Open Architecture for the Public Sector

#diggovreview #publicsectorIT .

Attended an interesting workshop last week to discuss some of the architectural aspects of Digital Government, hosted by Skyscape. One purpose of this discussion was to feed into the Labour Party Digital Government Review, and possibly into the Labour manifesto for the next election. Under modified Chatham House rules, I believe I am permitted to blog about the workshop as long as I don’t attribute anything to anybody or any organization.

There are several architectural themes that are probably shared between the political parties, although there may be some differences of emphasis and interpretation. For example, everyone seems to pay lip service to the idea of opening up public sector IT, and reducing the power of the incompetent and self-interested, whoever these may be. But there will undoubtedly be different views on the right tactics for redistributing commercial and bureaucratic power.

Openness leads to fashionable ideas about IT acquisition – a preference for consuming rather than self-build, and a preference for agile development rather than waterfall. These are great ideas when used properly, but we must be careful not to encourage the illusion that these ideas provide a magic solution to the troubles of public sector IT. Indeed, some recent IT disasters have been attributed to an ill-considered rush to “Agile”. And the Buy-Not-Build agenda must be governed properly, to avoid ceding too much architectural control to the large platform providers.

Openness also means structural change. For example, a shift from vertical integration and vertical silos to lateral modularity and co-creation, which my friend and associate Philip Boxer calls Collaborative Composition. This connects with the notions of Shared Services and Platform.

Finally, there is the question of the tempo of change. Government policies have a fairly rapid cycle time – in some cases around 18-24 months depending on department – but we cannot afford to reengineer systems and services, let alone platforms, at this sort of frequency.

So there was considerable discussion about the role of Government in providing a platform, and whether the platform should be a Minimum Viable Platform (similar to the Internet) or provide added value. There was also some debate as to whether politicians could be persuaded to support systems and platforms that would last longer than the policies that they were intended to implement.

The Public Sector suffers, perhaps even more than other organizations, from a confusion between Requirement and Solution. So people like to talk about Open Standards or Agile as the solution to high IT costs, or advocate Big Central Database as the perfect solution to any information needs, instead of talking about the requirements, such as interoperability and low switching costs. I hope that the Labour Party (or any other party for that matter) can be encouraged to express its policies in terms of the requirements and governance approach, rather than mandating specific technological solutions.

As I’ve pointed out before, the term “Joined-Up Government” has several different interpretations. From an Inside-Out (supply-side) perspective, it is commonly taken to imply improved integration between separate government departments and agencies – in other words, some kind of reorganization, not merely of IT systems and services but also the agencies responsible for these services. Of course, reorganization might sometimes be needed, but this is merely one possible solution to the real requirement, which in my opinion comes from the Outside-In (demand-side) perspective – the citizen’s need for a coherent experience of government services.

For example, the much-discussed integration between Healthcare and Social Care doesn’t entail merging two massive and inefficient silos into one even more massive and inefficient silo, but could be achieved simply by opening up the silos and improving the flows of information between them. The Outside-In perspective merely calls for the citizen to get a coherent joined-up service across both healthcare and social care, however this may be done.

And consider the much maligned Contact Point, which had somehow morphed from an information sharing platform (“System of Engagement”) to a Big Central Database (“System of Record”), largely under the control of people who didn’t appreciate that these weren’t necessarily the same thing.

Effective multi-agency working depends on effective information sharing, but this doesn’t mean putting all the data into a single source of truth. Many of the breakthroughs of Digital Government have come, not from building massive central databases, but from improving collaboration between different agencies – health, social care, police, justice, etc – often dealing with the same problem families from different professional perspectives. As we say at Glue Reply, it’s about the conversation.


Some of us have been talking about these themes for a long time. In my own small way, I have written a number of articles and blogposts about eGovernment and Joined-Up Government, and I submitted something on Shared Services to the Cabinet Office in January 2006, most of which is probably still valid. See previous posts on this blog – eGovernment, Joined-Up, Shared Services.
