MIL-HDBK-115 Us Army Reverse Engineering Handbook Guidelines And ProceduresThis HANDBOOK, which provides the guidelines and procedures for performing reverse engineering, was created using current applicable laws and knowledge gained during a trial program from July 1985 to April 1987, and is based on experiences obtained from military and industry participants. This handbook is for guidance only and cannot be cited as a requirement.

MIL-HDBK-115B(ARMY)

5.33 Make-or-buy. Where necessary, depending upon contractual agreements, a make or buy decision may be required by the government or contractor based on prototypes. Validation of the TDP during prototyping is important.

5.34 Schedules. New schedules should be developed based upon delivery times quoted for both the prototypes and production quantities.

5.35 Should-cost.

5.35.1 Data development. Should-cost data may be developed using actual quotations from suggested sources of supply developed during the procurement process.

5.35.2 Actual costs and schedules. The reverse engineering cost estimate and schedule (see. 5.11) should be updated to reflect the actual costs and schedules resulting from the production review.

5.35.3 Results. The candidate file should be updated to include the results of the production review.

5.36 Prototype production.

5.36.1 Prototype production objective. Prototype production involves the manufacture and testing of the prototype to determine if it meets all required specifications.

5.36.2 Sub-contracting. All prototype manufacturing should be sub- contracted to prove the adequacy of the preliminary TDP. When assembly and testing procedures are part of the TDP, the entire assembly should be completed. Testing that is not a normal function of the manufacturing industry may be sub-contracted.

5.36.3 Record maintenance. A record should be maintained of all subcontractor requests for waiver or deviation, and the cognizant engineer should review all such requests. All discussions with the vendors should include participation by the cognizant contracts or procurement personnel.

5.37 Procurement. A decision to procure the individual prototypes for test, as opposed to a first article test in a production run, should be the result of an economic analysis considering delivery times and tooling costs.

5.38 Parts fabrication. When an item is a relatively simple assembly, consideration should be given to procuring the parts individually and assembling the items in-house.
