50.5.1 Supportability analysis
interface. It is essential to conduct a Logistic Support Analysis or
other supportability analyses (Subtask 201.2.1)
early in an acquisition program to identify constraints, thresholds, and
targets for improvement, and to provide supportability input into early system
tradeoffs. It is during the early phases of an acquisition program that the
greatest opportunity exists to influence the system design from a
supportability standpoint. These analyses can identify supportability and
maintainability parameters for the new system which are reasonably attainable,
along with the prime drivers of support, manpower, personnel and training,
cost, and readiness. The drivers, once identified, provide a basis for
concentrated analysis effort to identify targets and methods of improvement.
Mission and support systems definition tasks are generally conducted at system
and subsystem levels early in the system acquisition process (Concept and
D&V phases). Identification and analysis of risks plays a key role due to
the high level of uncertainty and unknowns early in a system's life cycle.
Performance of these tasks requires examination of current operational systems
and their characteristics as well as projected systems and capabilities that
will be available in the time frame that the new system will reach its
operational environment. New system supportability and supportability related
design constraints must be established based upon support systems and
resources that will be available when the new system is fielded. Additional
guidance may be found in the Testability Requirements Analysis Handbook (20.1).
