Scrum software development is an iterative, incremental framework. Scrum structures product development in cycles of work called Sprints, iterations of work which are typically 1-4 weeks in length, and which take place one after the other. The Sprints are of fixed duration – they end on a specific date whether the work has been completed or not, and are never extended. At the beginning of each Sprint, a cross-functional team selects items from a prioritized list of requirements, and commits to complete them by the end of the Sprint.
During the Sprint, the deliverable does not change. Each work day, the team gathers briefly to report to each other on progress, and update simple charts that orient them to the work remaining. At the end of the Sprint, the team demonstrates what they have built, and gets feedback which can then be incorporated in the next Sprint.
Scrum emphasizes producing working product at the end of the Sprint is really “done”; in the case of software, this means code that is fully tested and potentially shippable.
