Maintainability Demonstration

The demonstration of the achievement of maintainability requirements has become an important contractual requirement, and each of the military services has published specifications describing their particular approach. With the existence of a number of specifications related to the same subject, contractors have been faced with the problem of becoming familiar with the requirements of each and adjusting their maintainability organization accordingly. The obvious solution is to issue one standard embodying the basic requirements of all the services. This paper will describe MIL-STD-471, ``Maintainability Demonstration,´´ prepared by a tri-service Department of Defense Task Group. It will describe, briefly, the background and problems leading to the development of the Standard, as well as its organization and the requirements and procedures contained therein.
