Mastering the Implementation and Management of Six Sigma Based on ISO 13053 Training — Lesson 3: Implementing Analyze and Improve: Causes, Hypotheses, Solutions, Pilots, and Risk

Learning Objectives

• Interpret the purpose, responsibilities, inputs, and decision points shaping implementing analyze and improve: causes, hypotheses, solutions, pilots, and risk.
• Apply the workflow and produce DMAIC analysis and improvement record that another practitioner can review.
• Analyze “a solution improves averages while increasing variation” and recommend a proportionate, evidence-based response.

Detailed Topics

• root-cause analysis
• statistical analysis
• hypothesis testing
• solution design
• pilot planning
• risk assessment
• benefit estimation
• stakeholder adoption
• Governance, competence, communication, documentation, validation, risk, and follow-up considerations

Instructor Demonstration

The instructor demonstrates the implementing analyze and improve: causes, hypotheses, solutions, pilots, and risk workflow, identifies applicable responsibilities, records checkpoints in DMAIC analysis and improvement record, and contrasts the accepted state with a condition where a solution improves averages while increasing variation.

Hands-On Exercise

Complete a controlled implementation, management, audit, assessment, foundation, introduction, awareness, or transition exercise for Implementing Analyze and Improve: Causes, Hypotheses, Solutions, Pilots, and Risk. Establish scope and criteria, collect or create evidence, examine “a solution improves averages while increasing variation,” reach a supported conclusion, and preserve the result in DMAIC analysis and improvement record.

1. Confirm objectives, scope, roles, criteria, stakeholders, and expected outputs.
2. Perform the planned activities while recording assumptions, evidence, and decisions.
3. Test a normal case, an exception, and a follow-up or improvement condition.
4. Document conclusions, owners, due dates, escalation, and verification requirements.

Scenario Analysis

• Identify the requirement or principle with the strongest influence on implementing analyze and improve: causes, hypotheses, solutions, pilots, and risk.
• Compare two defensible responses and explain their governance, risk, and evidence trade-offs.
• Determine how the DMAIC analysis and improvement record should be approved, retained, reviewed, and updated.

Troubleshooting Guidance

Separate missing evidence from ineffective practice, and distinguish a documentation issue from a control, process, governance, or competence failure. Use DMAIC analysis and improvement record to trace the earliest divergence. Treat “a solution improves averages while increasing variation” as a hypothesis until the response is validated against the applicable requirement and intended outcome.

Validation Checklist

• The scope, criteria, stakeholders, and intended outcome for implementing analyze and improve: causes, hypotheses, solutions, pilots, and risk are explicit.
• The DMAIC analysis and improvement record links statements and decisions to objective, reviewable support.
• Responsibilities, competence, communication, risk, legal duties, and change impact were considered where relevant.
• Findings, corrective actions, monitoring, review triggers, and improvement ownership are clear.

Lesson Outcome

Learners can apply Implementing Analyze and Improve: Causes, Hypotheses, Solutions, Pilots, and Risk, explain the reasoning used, and defend the result through DMAIC analysis and improvement record.
