Method for creating a process capability database

摘要

A procedure and method for eliciting expert information on process capability and thereafter manipulating the elicited information in such a manner that it can effectively be used in a process capability database that is operating in a six sigma regime. The manipulation preferably includes converting (240) the expert elicited information (230) from a tolerance-type metric to a short term standard deviation (or sigma) metric (240), whereby the result of the manipulation is used (254) to populate directly a process capability database (210) and, as appropriate, thereby augment, replace or modulate the data already stored therein. <IMAGE>
