Measure Phase: Understanding the process

The expression "Measure" in the DMAIC cycle is perhaps overly restrictive.

During this phase we are exploring the process, of which measurement is an important, but not sufficient, part.

Before we can begin to measure, we need to develop our insights and theories as to what is important to measure: measurement is neither easy nor cheap.

At the end of the Measure phase, we should expect to have:

  • a sufficiently detailed view of the process to identify problem areas (quality concerns);
  • a clear understanding of customer and business requirements for satisfactory process performance;
  • adequate measures and data to support assessment of process variability and future expectations;
  • effected immediate improvements;
  • eliminated assignable (special) causes - i.e. to have the process in a state of control.

Here are the main activities involved in the Measure phase:
