MIL-HDBK-502: ACQUISITIONALOGISTICSthe commercial support system. For those system elements for whichorganic support is required:• Identify hardware candidates and support functions.• Conduct repair analysis.• Perform functional analysis and task analysis on repairable items forselected support system design.The available design data and the operations and support concepts shouldbe analyzed to identify the hardware design repair candidates and the basicfunctions that should be supported (FA/A segment of the systemsengineering process). Analysis should be performed to establish a repairversus-discardand a level-of-repair policy for each repairable item undereach of the support concepts. This repair level analysis should be used torecommend the optimum repair policy and level of repair for the item basedupon system availability life cycle costs (Synthesis and SA&C parts of thesystems engineering process). Based upon the results a support systemdesign can be selected.Repairable items should be functionally analyzed under the selected supportsystem design to identify specific corrective, preventive, and otheroperations and support tasks (FA/A segment of the systems engineeringprocess). Tasks should be analyzed to identify their annual frequency,manpower and personnel requirements, elapsed times, task procedures,spare and repair parts, test equipment—in short, all logistics resourcesneeded to perform the task (Synthesis part of the systems engineeringprocess). Factors that relate system characteristics to support taskrequirements like annual frequency and hardware reliability should be easilytraceable to ensure that the impact of any changes can be recognized andaddressed (SA&C portion of the systems engineering process). Supportfactors such as manpower requirements and sparing rates should be relatedto hardware oriented maintenance planning factors like the annualoperating requirements of the system and the individual task frequencies.This action maintains the linkage between requirement, design, andsupport. The detailed task information should be used as the source ofinformation for preparing required logistics data products.A notional supportability analyses process flow for a Commercial/NDIacquisition is shown in Figure 5-1.5-9
