The second phase in the Six Sigma Define-Measure-Analyze-Improve-Control (DMAIC) methodology is Measure. In a previous post, we discussed the Define Phase in the Six Sigma DMAIC Methodology.

During the Measure phase, the focus shifts from “do we agree that X is a problem” to “what’s the phenomena that is happening such that it is a problem?” For example, if a machine is failing, it would be good to know how often, when it’s failing, and other items related to the defect.

In other words, collect data.

But, it’s not just data. It’s gut or hunch also.

Here’s what I mean: often times, we begin with “hunch” or “gut” and that gives us a good place to start of where to collect data. Ideally, we want to marry our gut hunch with data.

Lean Six Sigma: Purpose of Measure (DMAIC)

• Through more detailed analysis, select a problem and problem space that will have the biggest impact on the organization and set an improvement target.

Lean Six Sigma: Tools used in Measure (DMAIC)

In the Lean Six Sigma phase of Measure, these are often the tools that are used:

1. Run Chart
2. Control Chart

1. Measurement System Analysis
2. Prioritization Matrix
3. Pareto Analysis
4. Spaghetti Diagram
5. Process Cycle Efficiency

Lean Six Sigma, Measure, Critical Checkpoints

• Plan for and document the results of data collection.
• Establish improvement targets.
• Stratify situation to a component level specific enough to analyze.
• Frame a problem statement clearly and simply, using data.
• Present data using appropriate descriptive charts and graphs.

Lean Six Sigma, Measure Tollgate Checklist

• How and where did you collect the data?
• Are you using attribute or continuous data and why?
• What does the distribution of your data look like?
• How repeatable and reproducible is your data?
• What is your sampling plan?
• How did you ensure randomness in your data collection?
• What is the current performance of the process?
• How did you establish your improvement target?

This constitutes a basic template for the Measure Phase in Six Sigma.
