Build a Usable Process Capability Database

Six Sigma Forum Magazine vol. 3 issue 4 - August 2004

Abstract: Design for Six Sigma requires that designs meet customer needs without sacrificing quality. A number of statistical tools can be used to produce process capability data to enable development teams to design products that can be produced at reasonable cost on existing equipment. However, setting up and using a process capability database is poorly understood and as a result, it is seldom used. To create a successful database, it is necessary to get management support, build the right data structure, collect the right data, and use the data correctly. A correctly designed database will allow the product development team to focus its efforts only on those tolerances in which the capability is unclear or in which function or cost improvements can be achieved.
