This diagram shows a 5 phase lifecycle of a system, from concept through delivery and deployment.  IT PM uses this model as a roadmap for project participants. Although the phases are sequential, the process steps within them may vary in order and are often iterative.  The model can also serve as a project repository; each process step links to a page containing a brief process map, guidelines, templates, checklists, and reference material. The model can also be tailored to specific organizational requirements, portfolio management issues, and the development of integrated product lines.  See the Introduction to the SDLC for more information.
