<strong>MIL</strong>-<strong>HDBK</strong>-<strong>502</strong>: ACQUISITIONALOGISTICSThe supportability analyses to be accomplished vary from program toprogram <strong>and</strong> from phase to phase. What supportability analyses need to beconducted is largely determined by two key factors—the acquisition phase<strong>and</strong> the type of acquisition.The acquisition process is controlled by the acquisition managementprocess. This process divides a program into a series of logical phases.Each phase targets specific issues <strong>and</strong> objectives which generally correlateto one of the engineering states of a design. The issues <strong>and</strong> objectivesreflect those which should typically be addressed before proceeding to thenext phase <strong>and</strong> state of design.Acquisition phases are separated by decision points at which total systemdesigns are reviewed <strong>and</strong> evaluated against phase issues <strong>and</strong> objectives.These decision points are Milestones 0, I, II, <strong>and</strong> III. Passing a milestonereview represents the decision approval to proceed to the next programphase. The acquisition management process phases are shown in Figure 4-1. However, the specific number of phases <strong>and</strong> the content of each arealigned with the particular needs of a program.Mission AreaAnalysisThe Acquisition Life CycleIdentification ofA Mission NeedDECISION<strong>MIL</strong>ESTONE 0Concept ExplorationDECISION<strong>MIL</strong>ESTONE IProgram Definition &Risk ReductionDECISION<strong>MIL</strong>ESTONE IIThe life cycle is tailoredto meet the particularneeds of theprogram.Engineering &Manufacturing DevelopmentDECISION<strong>MIL</strong>ESTONE IIIFigure 4-1.
