The CMS Integrated IT Investment & System Life Cycle Framework (ILC) can be viewed as a hierarchy with the IT Investment Management phases as the top layer. The next layer of the ILC is the Project layer and distinguishes those activities performed across the three primary stages of an IT project; Pre-Project, Project and Post Project. The Pre-Project phase consists of activities geared towards the conceiving, approving, and launching of a new project. The Project phase includes tasks needed to effectively plan and execute the system. Post Project phase is where ongoing monitoring and potential termination of the application occurs. The final layer of the ILC is the System layer and integrates the traditional system life cycle activities and is based on the IEEE/EIA 12207 industry standards for system engineering. As a result, the activities that comprise the CMS system life cycle are referred to collectively in terms of ten (10) lifecycle phases, which are as follows:
1. Initiation Phase
2. Concept Phase
3. Planning Phase
4. Requirements Analysis Phase
5. Design Phase
6. Development Phase
7. Test Phase
8. Implementation Phase
9. Operations & Maintenance Phase
10.Disposition Phase While the phases of the ILC are graphically depicted in sequential order, some of the phases may overlap or may be iterative depending upon the system development methodology selected for the project.
