Measure Stage

The objectives of the measure phase are explained and illustrated in this chapter.

Objectives

The objectives of the measure stage include

• Process definition at a detailed level to understand the decision points and
detailed functionality within the process.
• Metric definition to verify a reliable means of process estimation.
• Process baseline estimation to clarify the starting point of the project.

• Measurement system analysis to quantify the errors associated with the
metric.

Process Definition

In the measure stage of the define, measure, analyze, improve, and control
(DMAIC) problem- solving methodology, a detailed process- evel map of the

current (i.e., as- is) process is developed. This detailed map clearly defines the
activities subject to the improvement efforts. The top- level process map devel-
