Best Practice : Development Program Configuration Control Process
McDonnell Douglas Aerospace (MDA)-St. Louis uses a system for documenting the product configuration during the design, manufacture, assembly, and test process. The system consists of two elements -- a monthly configuration update matrix and a document that contains a top-level description of the aircraft.
The monthly configuration update matrix reflects the change board decisions that affect the aircraft configuration. The configuration matrices allow MDA-St. Louis to quickly identify all aspects of the design configuration that could potentially be affected by any change. This enables MDA-St. Louis change boards to document design notes, loft definition, and trade studies to provide a common definition of the current product configuration across the product design community. It also provides a single configuration baseline for the monthly Technical Performance Measurement (TPM) process which assesses design maturity/requirement conformance.
The Configuration Description document is periodically reissued to reflect the cumulative impact of the change board decisions on the actual design. The monthly update matrices defined the changes that impact the configuration definition. This documentation contains text and graphics portraying the air vehicle, airframe, subsystems, avionics, armament, new technology, and flight test installations. It is updated to support key program milestones, ranging from Critical Design Review to Low Rate Initial Production (Figure 2-1). This process can track multiple design baselines from actual through planned configurations.
