I often hear a question: what is better, Agile or RUP? This question doesn't make a lot of sense since Rational Unified Process (RUP) is a framework with a large set of artifacts, processes, roles, and procedures; while Agile is a short list of philosophical points. I would actually strongly recommend you study RUP to understand software development (or even get certified). XDSD is our philosophy and Zerocracy is a framework.
