Be pragmatic in software development is rarer than one would expect or hope. I've seen all sorts of craziness throughout the years. Architects, analysts and developers doing and believing things that simply made no sense in any worlds. Using examples from my experience, I will teach you tricks to really be pragmatic. This will allow you to quickly develop software that people really want to use. Whether you are a manager or a developer, you should find it useful.
