        We just discussed the NEW version (DODI 5000.2)
        Some Major Differences:
                Concept & Technology Development are separated by MS-A
                Name of the final Phase Changed
                Some new Milestones
                MNSs and ORDs are replaced by ICDs and CDDs
                Others
        As such, although many of the specifics of Chapter 2 are
         dated, the general approach described for iterative
         application of the SEP process to the DoD Acquisition
         Phases is still valid.
        Chapter 2 Conclusions are still valid.

           2.5 Summary Points
   The development, acquisition, and operation of military systems is governed by a multitude
    of public laws, formal DoD directives, instructions and manuals, numerous Service and
    Component regulations, and many inter-service and international agreements.
   The system acquisition life cycle process is a model used to guide the program
    manager through the process of maturing technology based systems and readying them
    for production and deployment to military users.
   The acquisition process model is intended to be flexible and to accommodate systems
    and technologies of varying maturities:
        Systems dependent on immature technologies will take longer to develop and produce,
        Systems that employ mature technologies can proceed through the process relatively quickly.
   The system engineering effort is integrated into the systems acquisition process
    such that the activities associated with systems engineering (development of
    documentation, technical reviews, configuration management, etc.) support and
    strengthen the acquisition process.
   The challenge for the engineering manager is to ensure that engineering activities
    are conducted at appropriate points in the process to ensure that the system has, in fact,
    achieved the levels of maturity expected prior to progressing into succeeding phases.
         S2-A Technology Readiness Levels
   New DOD 5000.2 Process requires a
    Technology Readiness
    Assessment (TRA) prior to
    Milestone B (for Major Acquisitions)
   Critical Technologies need to be
    identified and characterized by
    Technology Readiness Level
   Chart to right provides definition for
    each level.
   For Milestone B, most (all) critical
    technologies should be at TRL 5/6 or
