Abstract
The application of Measurement Systems Analysis (MSA) is increasingly important in precision industry and the role of metrology is considered vital in the safety critical environment sectors such as radiotherapy, nuclear power and aerospace. MSA is enabling the creation of extensive knowledge and understanding to the entire envelope of these sectors.

Within these business sectors the availability of statisticians and expert practitioners is freely available. However the associated supply chains of these business sectors exhibit the practices created by the lean operations drive which has promoted all forms of verification and measurement as “non value added” (NVA). Thus the concept that a NVA process is underpinned by a series of “complicated” statistics has arguably provided an excuse for it to be ignored.

An investigation into the current accepted practice within the SME activity would unveil many instances of disagreements between entities of the supply chain where contrasting measurements have been obtained. The resolution over which measurement is correct potentially erodes reduced profit margins further.

The ongoing demand for waste/NVA reduction and “cost down” activity could be achieved through the dissemination of MSA into various organisational interfaces. Linking the process improvement activity to the MSA arena to statistically evaluate confidence levels within organisation interacting measurement systems and thus align the process capability of measurement systems to ultimately enable Muda reductions.

This paper evaluates the theoretical problems arising from measurement systems misalignments and shows a need for a generic MSA framework which supports the relevant lean philosophy.
