The aim to deliver valuable software is a great, core principle of the agile movement. The difficulty however is that ‘value’ in itself is hardly quantifiable. Yet, I do believe it is imperative to think in terms of value in software development and therefore overcome some fluffiness attached to ‘value’. If we don’t find actionable ways to deal with ‘value’ it might remain meaningless; another buzz word, another way of getting people to think it’s time to move on to the next hype. It is not only difficult to quantify value, it is not even necessary, maybe even undesirable. It is better to measure whether we are delivering value (effectively).
What we thought defined success
For many years we were tricked into believing that software development can be considered a success if we meet 3 criteria: deliver (1) all promised requirements (2) within the planned time (3) for the allocated budget. It is reflected in the famous iron triangle of software development.
That in turn tricked us into believing that, in order to be successful, we had to exhaustively analyze, detail and describe all requirements upfront, and get formal approval and sign off over them before the actual programming can be done. The underlying motivation is to secure the first element of what we were told defines success, the ‘requirements’. [Continue reading...]
