Both Boeing and the supplier can identify key characteristics and key process
parameters. Boeing identifies key characteristics to aid in product assembly,
performance or service life. The supplier may identify key characteristics for
the same reasons, but they may also identify key characteristics to aid
producibility and productivity -- that is, to help reduce internal waste,
assembly time, labor, cycle time, inventory, and so on (see requirement
4.1.3).
An example AQS Control Plan is shown in Figure 6.3.1. The AQS Control
Plan is a form used for documenting relevant AQS information on parts and
processes. The first major category includes information regarding key
characteristics and key process parameters, followed by information
regarding the control of variation, process capability, gage information and
sources of process variation. It should be updated as necessary (see the
AQS Control Plan section in D1-9000-1, AQS Tools.) The AQS Control Plan
includes a basic measurement plan. Suppliers may use the AQS Control Plan
or an equivalent format that contains the same information.
