Product Supportability Issues in the Early Design Phases.

摘要

The goal of the Unified Life Cycle Engineering (ULCE) program is to develop enhanced design environments that will allow considerations of producibility and supportability of the product to be made early in the design process along with the usual factors of performance, cost, and schedule. This paper documents the issues involved with integrating consideration of product supportability in the early design phases. It contains a thorough description of the acquisition/design process for a selected hardware design problem, an airborne radar warning, and countermeasures equipment. The major performance design goals and requirements typically considered in the design process for the selected equipment are given in detail; the measures for reliability, maintainability, and supportability (R,M&S) used at each level of the equipment breakdown are documented, and the shortfalls in the acquisition requirements documents that prevent the design process from ensuring a supportable product are identified. Specific recommendations are given for facilitating the consideration of supportability requirements. Appendices contain sample specification paragraphs for development specifications for use as a guide to specification preparation and sample paragraphs for use as a guide for Statement of Work preparation.
