This document discusses Scrum, an agile approach to software development. It outlines problems with traditional waterfall development models, such as unclear requirements and wasted time. Scrum uses short iterative cycles, a product owner to represent customers, self-organizing teams, and a scrum master to guide the process. The results of using Scrum can include more flexible scope, faster delivery, higher quality products, better progress visibility, less waste, and happier development teams.
