The core principles of the Scrum Manifesto, and why it gained such a cult following, are <strong>reflection and continuous improvement</strong>. The purpose of Scrum is to tighten the iteration cycle and hold a retrospective at the end of each cycle, in which you analyze and adapt the process to continuously improve. This tight feedback loop allows teams to gel quickly, establish an efficient process, eliminate waste, and adapt to changing priorities easily. This is what makes agile development so great.
