Overview/Description
The Six Sigma® DMAIC system is a roadmap that shows the way to process and performance improvement. The second phase in the roadmap, the Measure phase, provides a methodology and tools for collecting data and establishing baseline measures of current processes. However, measurement itself can be problematic. A measurement system is only as good as the measuring instruments and the operators, and both are responsible for a certain amount of variation. An important part of process improvement--conducted before collecting measurement data--is analyzing the measuring system to ensure that measurements are made without bias, are reproducible by all measuring instruments, and are repeatable by all operators. In this course, you will learn about Measurement Systems Analysis (MSA). You will see how to assess properties of a measurement system, including how to plan and conduct a Gauge R&R. You will learn some important principles of metrology and learn salient features of some common measuring instruments, including gauge blocks, calipers, and micrometers, among others.

Target Audience
Candidates for Black Belt certification; managers/executives overseeing personnel involved in the implementation of Six Sigma in their organization; consultants involved in implementing a Six Sigma proposal; and organizations implementing a Six Sigma project
