This report tracks DOD involvement in and development of a category of warranty which seeks good product reliability and also reliability growth or growth potential (called RIW) that has evolved over a number of years from DOD and industry experiences. The report provides a historical trail leading to RIW as used in DOD with primary emphasis on the Air Force's recent experience. Some commercial airlines' warranty concepts are discussed; then government and industry views are presented. The report details CODSIA involvement and role in RIW structuring and usage during the current DOD trial test of the concept-- started in 1973. In 1974 it was further definitized and the term RIW and its concepts were presented for the trial use project. However, no specific trial/test parameters have been established. Currently the individual services may apply RIW as they determine, within overall DOD guidelines. Achievement or consummation of the assessment of RIW's merit, benefits, hazards and policies is the task that DOD is at grips with now. The author suggests alternatives to the current DOD RIW test approach, and recommends that: (1) the test be formalized for a period of 1 more year or less; (2) the current RIW programs be evaluated in depth and new programs be added very selectively (or not at all); and (3) DOD, CODSIA and ARINC coordinate or compromise on implementation details and contractual provisions based on the findings of the 1-year test (if RIW is approved as a concept for continued use).
