Unformatted text preview: ject life cycles have similar phase names with similar deliverables required, few are identical. Most have four or five phases, but some have nine or more. Even within a single application area, there can be significant variations--one organization's software development life cycle may have a single design phase while another's has separate phases for functional and detail design. Subprojects within projects may also have distinct project life cycles. For example, an architectural firm hired to design a new office building is first involved in the owner's definition phase when doing the design, and in the owner's implementation phase when supporting the construction effort. The architect's design project, however, will have its own series of phases from conceptual development through definition and implementation to closure. The architect may even treat designing the facility and supporting the construction as separate projects with their own distinct phases. Project Project Management Management Body of Body of KnowledgeE L KnowledgeE PL 2.1.3 Representative Project Life Cycles The following project life cycles have been chosen to illustrate the diversity of approaches in use. The examples shown are typical; they are neither recommended nor preferred. In each case, the phase names and major deliverables are those described by the author for each of the figures. Defense acquisition. The United States Department of Defense Instruction 5000.2 in Final Coordination Draft, April 2000, describes a series of acquisition milestones and phases as illustrated in Figure 2-2. Concept and technology development--paper studies of alternative concepts for meeting a mission need; development of subsystems/components and concept/technology demonstration of new system concepts. Ends with selection of a system architecture and a mature technology to be used. System development and demonstration--system integration; risk reduction; demonstration of engineering development models; development and early operational test and evaluation. Ends with system demonstration in an operational environment. Production and deployment--low rate initial production (LRIP); complete development of manufacturing capability; phase overlaps with ongoing operations and support.
