Measure stage objectives include (Keller, 2011a):
• Process definition. Define the process at a detailed level including decision points and functions.
• Metric definition. Define metric to reliably establish process estimates.
• Process baseline. Use the defined metrics to establish the current state of the process, which should verify the assumptions of the Define stage. Determine whether the process is in statistical control.
• Measurement systems analysis. Quantify errors associated with the metric.
