Most organisations go through an architecture modernisation effort at some point as their systems drift into a state of intolerable maintenance costs and they diverge too far from modern technological advances. High-level Process Sections Conceptually, there are three major sections to a modernisation process.

OS X, which used to trumpet “It just works,” has evolved to “it used to just work”; the most user-centric Unix-like system ever built now staggers under the load of new and poorly thought-out features. Most professional programmers work on large systems that can consist of thousands of functions and millions of lines of code.

It’s much better to build your process around quality checks than retrofit these checks into the existent process. NIST did classic research to show that catching bugs at the beginning of the development process could be more than ten times cheaper than if a bug reaches production. However, it’s not a unit test. A side note.

This kata is split into four sections that address different aspects of architecting software systems. All architecture decisions are ultimately driven by a company’s business model, so I think this is a sensible starting point. I’ve used it a few times now and it seems to have worked well so I thought it would be good to share.

One of the biggest time costs in software development is understanding how a system works. Systems are getting more complex yet our ability to understand them doesn’t seem to be growing at the same rate. As we continuously develop software systems, the complexity slowly increases and we don’t fully realise it.
