Measurement Systems Analysis

Evaluate a Continuous Measurement Process Using the EMP Method

The Measurement Systems Analysis (MSA) platform uses the Evaluating the Measurement Process (EMP) method to assess the precision, consistency, and bias of a measurement system. Use MSA to evaluate your measurement system performance. Before you study the process itself, you should make sure that you can accurately and precisely measure the process.

Note: This chapter covers the EMP method. The Gauge R&R method is described in Variability Gauge Charts.
