Dallas, June 2, 2003 – Today there are a remarkable number of interesting C# presentations at TechEd. The day started with “Extreme Programming with C#” presented by Ken Schwaber. Of course is Extreme Programming as a method independent from any programming language, however, it was interesting to listen to Schwaber’s experiences in this area. No longer waiting for twelve months for applications that nobody really wants, but every thirty days working deliveries, slowly but surely moving towards the end goal. It becomes accepted that it is impossible to specify large, complex software projects entirely. According to Schwaber it makes much more sense to have some idea of what an application’s functionality needs to be and to refine that idea by frequent iterations. The goal of the iterations is to deliver working solutions from day one with a frequency of about four weeks. In this way it is possible to always have a running system. After some time the functional requirements become clearer and clearer. The amount of work per iteration is not too much and having regular feedback with the client is a clear benefit. Schwaber is a big promoter of software code that is documentation at the same time. Test first development is absolutely necessary, with the advantage that the test automatically becomes a low level design of the functionality. During iterations a software development team has its own responsibility for reaching milestones, delivering good quality software and delivering the desired functionality. The team decides in a scrum (a short meeting) what the next things to implement will be. This approach has also been used during the development of .NET functionality at Microsoft.
