1. DMAIC: Measure
Robert Setaputra

2. Measure
The measure phase begins with the identification of the key process metrics.
Once the key process metrics have been specified, related process and customer data is collected.

3. Purpose of Measure Phase
To validate the data
To help the team narrowing the range of potential causes need to be investigated in Analyze phase.

6. Gage R&R Repeatability & Reproducibility (R&R) Repeatability
Variation that is due to the measurement device (same operator, same part, same device).
Within person variation.
Reproducibility
Variation that is due to the measurement system (different operators, different parts, same device).
Between person variation

7. Gage R&R Study Design (Crossed Design)
Select a set of representative parts.
Select a group of operators to measure the parts.
Ask the operators to measure for each part repeatedly.
Ex. 5 parts, 2 operators, and 4 replicates.
