Article Abstract

Fact finding, review, and implementation were the three phases used by Lockheed Martin Manned Space Systems to build quality into the processes and hardware products of its space shuttle program. This was called a process-product integrity audit (PPIA). Phase I of the audit included an examination of design requirements, job instructions, and production stages as well as root cause analysis and subsequent corrective action recommendations. The Phase I team prioritized its findings into three categories. Phase II was a review by a new team of the Phase I team's corrective action suggestions, categorizations, and cause analysis. Changes recommended in Phase II required approval of the Phase I team. In Phase III, the corrective actions were implemented. The PPIA is appropriate for evaluating the match between work instructions and operation requirements.
