No one can deny that the evolution of software process processes towards the Agile/agile philosophy hasn't transformed the way in which we develop software. Agile brings all kinds of benefits like closer interaction with the customer, faster time to market, quicker turnaround times from requirements to solution etc. But there is an underlying denial of what is being delivered in some aspects. This denial is in the level of documentation. Nothing in the Agile manifesto says don't document your architecture, analysis or designs. It's about getting the right level of documentation. But we encounter in many organisations a complete lack of documentation. Consider the following questions regarding your organisations approach to its SDLC (Softwware Development Life Cycle)

All of these approaches lead to fantastic ways to develop and maintain software components and in actual fact it's quite easy to determine some aspects of the problem being solved by looking at the tests. More so with ATDD and BDD and not necessarily with TDD on its own. The problem is, when you have a system that is comprised of many components, none of these techniques actually describe the complexity and thinking behind the design of the components and their inter-relationships. You would need to statically and dynamically walk through the code. Depending on your level of experience in the language this could be done quickly. However, there is nothing stopping you from making some very bad assumptions regarding what the software is actually doing.

Once we gain access to your software, we will develop some ATDD tests to help define the requirements (we only do this if no ATDD tests already exists). We will then work through your software and develop a number of UML models such as class, sequence, activity, state, deployment, and component diagrams etc. of your softarware software with accompanying textual narrationnarrations. We then finally use a number of techniques to determine the best way to present the models in a manner that suits the way you work.
