SCRUM Methodology
nThe first and last phases (Planning and Closure) consist of defined processes. nThe Sprint phase is an empirical process. It is treated as a black box that requires external controls. nSprints are nonlinear and flexible. Sprints are used to evolve the final product. nThe project is open to the environment until the Closure phase. The deliverable can be changed at any time. nThe deliverable is determined during the project based on the environment.
