Six Sigma Green Belt – PECB — Lesson 2: Measure Systems, Process Capability, Data Collection, Mapping, and Baseline Analysis

Learning Objectives

• Interpret the requirements, principles, roles, and dependencies shaping measure systems, process capability, data collection, mapping, and baseline analysis.
• Apply a practical workflow and create a reviewable measurement and capability workbook.
• Evaluate the exception where measurement systems introduce unacceptable variation and determine proportionate follow-up.

Detailed Topics

• Measure Systems applied to the course scenario and expected evidence.
• Process Capability applied to the course scenario and expected evidence.
• Data Collection applied to the course scenario and expected evidence.
• Mapping applied to the course scenario and expected evidence.
• and Baseline Analysis applied to the course scenario and expected evidence.

Instructor Demonstration

The instructor traces a case involving an operations function improving a high-volume process with recurring defects, delays, capacity constraints, and customer dissatisfaction. The demonstration links decisions to objective evidence, records the result in measurement and capability workbook, and tests the condition where measurement systems introduce unacceptable variation.

Hands-On Exercise

Complete a controlled exercise covering Measure Systems, Process Capability, Data Collection, Mapping, and Baseline Analysis. Confirm scope and responsibilities, examine the stated exception, reach a supported conclusion, and preserve the outcome in measurement and capability workbook.

1. Define the objective, boundaries, stakeholders, criteria, and expected work product.
2. Perform the activity while recording assumptions, observations, evidence, and decisions.
3. Test normal operation, the exception, and an escalation or follow-up condition.
4. Document conclusions, owners, deadlines, verification methods, and review triggers.

Scenario Analysis

• Identify the requirement or control with the strongest influence on the scenario outcome.
• Compare two defensible responses and explain their risk, operational, and evidence trade-offs.
• Decide how the measurement and capability workbook should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Start where expected practice and observed evidence first diverge. Separate a missing record from an ineffective process, distinguish unclear ownership from a control failure, and treat “measurement systems introduce unacceptable variation” as a hypothesis until tested against the applicable criteria and intended outcome.

Validation Checklist

• Scope, roles, criteria, stakeholders, dependencies, and intended outcomes are explicit.
• The measurement and capability workbook connects conclusions to objective, reviewable support.
• Normal operation, the stated exception, escalation, and follow-up were evaluated.
• Owners, due dates, verification methods, review triggers, and improvement actions are clear.

Lesson Outcome

Learners can apply Measure Systems, Process Capability, Data Collection, Mapping, and Baseline Analysis, explain the reasoning used, and defend the result through measurement and capability workbook.
