MIL-HDBK-115B(ARMY)
5.1.2 Recommended changes. As a result of the reverse engineering effort, product improvements or value engineering changes may be recommended (see 5.46). These alternatives may be considered during the reverse engineering process and may be incorporated prior to completion of the process.
5.2 Functional/economic analysis. A Functional/Economic Analysis should be accomplished to collect available documentation, determine missing data requirements, determine testing requirements, and develop the reverse engineering cost-estimates and schedules.
5.3 Data collection.
5.3.1 Documentation. A competitive TDP should include all the documentation necessary to describe the design configuration, manufacturing, quality assurance, testing, and packaging requirements of the equipment. The TDP for a reverse engineering candidate may include restricted or inadequate end-item documentation and drawings which must be developed through engineering analyses of existing hardware.
5.3.2 Data collection phase. The purpose of the Data Collection phase is to secure all the unrestricted documentation available, to preclude unnecessary duplication and to facilitate the development of technical documentation through reverse engineering. The following data is desirable:
a. Next higher assembly, which provides information on input/output parameters, mating parts, end-use, etc;
b. Specifications, such as Test Specifications; Acceptance Test
Procedures, Purchase Descriptions, etc;
c. Parts list/data list, which identifies all parts and indicates if they are standard National Stock Numbers (NSNs), Military Standard (MIL-STD) parts, etc. The Data List should indicate the applicable drawings and specifications necessary and provide valuable information on specifications that should be researched to remove restrictive requirements;
d. Schematics, which provide basic information for the Physical Configuration Audit (PCA), verify the parts list, and save time in tracing circuitry (i.e., Printed Circuit Board (PCB) wiring);
e. Master pattern drawings, which provide copies of the mylars, saving both time and the cost of re-drafting; and
