Architecture and Agility

Last night I had an inspiring dinner with one of my old colleagues, Ronald Doelen. We both see more and more companies changing their project methodology from waterfall to agile. We're both very enthusiastic about that, even though there are some hurdles to take, like architecture for example.

All and good to go Agile, but if you're stuck in an analysis-paralysis situation with your architecture, you will not reap the benefits that Agile brings. You might get away with ignoring the architecting issue - at least for the short term - but it will catch up with you in due course.

So, the answer: Agile Architecture. That got a nice ring to it, but what and how? It all depends on how you look upon architecture and the role of the architect in the company. At the end of our meal - not quite as good as our discussion, tbh - we came up with a number of statements that we'll take with us to work on in the near future. Let me share a few of our thoughts:

The role of the architect in your organization is often determined by the culture of your organization. The architectural style (ivory tower, magician, counsellor, architectus reloadus) determines how you need to adapt your agile projects to align with architecture. The more agile the architect, the less impact.

Architecture is nothing more (or less) than a (limited!) set of choices and the accompanying motivations. Often architects worry about making the best choice. In case you didn't know it yet: there IS NO BEST CHOICE! There's just choices, all with consequences. Use risk-analysis to determine short and long term implications of your choices and base your trade-offs on them. But limit the choices to those you really need NOW.

I'll spend some more time thinking about Agile architecture and especially how to align Enterprise Architecture with Agile projects. I still see some challenges, but will take about those later.
