The Physical Configuration Audit (PCA) verifies that the physical configuration of the system corresponds to the approved "build-to" (or "code-to") documentation. The Functional Configuration Audit (FCA) verifies that the acceptance verification (usually, test) results are consistent with the approved verification requirements. (See Section 4.8.4.) In-Process Inspections. The extent, timing, and location of in-process inspections are documented in the quality assurance program plan. These should be conducted in consonance with the manufacturing/fabrication and verification program plans. (See Sections 6.6 and 6.7.) QA Survey. A QA survey examines the operations, procedures, and documentation used in the project, and evaluates them against established standards and benchmarks. Recommendations for corrective actions are reported to the project manager. Material Review Board. The Material Review Board (MRB), normally established by the project manager and chaired by the project-level quality assurance engineer, performs formal dispositions on nonconformances. 6.4 Maintainability Maintainability is a system design characteristic associated with the ease and rapidity with which the system can be retained in operational status, or safely and economically restored to operational status following a failure. Often used (though imperfect) measures of maintainability include mean maintenance downtime, maintenance effort (work hours) per operating hour, and annual maintenance cost. However measured, maintainability arises from many factors: the system hardware and software design, the required skill levels of maintenance personnel, adequacy of diagnostic and maintenance procedures, test equipment effectiveness, and the physical environment under which maintenance is performed. 6.4.1 Role of the Maintainability Engineer Maintainability engineering is another major specialty discipline that contributes to th...
