Assess Measurement Systems
The Measurement Systems Analysis Platform
The Measurement Systems Analysis (MSA) platform assesses the precision, consistency, and bias of a
measurement system. Before you can study the process itself, you need to make sure that you can accurately
and precisely measure the process. If most of the variation that you see comes from the measuring process
itself, then you are not reliably learning about the process. Use MSA to find out how your measurement
system is performing.
This chapter covers the EMP method. The Gauge R&R method is described in the “Variability Charts”
chapter on page 151.
