Study Notes

Problem-Solving Framework

Utilize the 5W1H method and Why-Why Analysis for identifying root causes.
Employ DMAIC (Define, Measure, Analyze, Improve, Control) approach for unearthing systematic flaws.
Need for Root Cause Analysis (RCA) if problems persist or are complex.

Key Concepts in RCA

Identify Obvious Causes: Utilize 5W1H and Why-Why methodology.
Explore Not Obvious Causes: Encourage cross-departmental collaboration for diverse insight.
Clarification of the Problem Statement is essential for focused analysis.

Steps in Why-Why Analysis

Start by asking “Why does the issue occur?” leading to a sequence of inquiries until the root cause is identified.
Document findings clearly and consider collecting additional data if necessary.
Avoid assigning blame and ensure team participation throughout the analysis process.

Guidelines for Analysis

Distinguish between an Incident, Problem, and Root Cause effectively.
Do not assume the 5th Why as the sole root cause; it might reside in earlier responses.

Implementing Solutions

Develop countermeasures that provide permanent fixes without compromising on safety, quality, or efficiency.
Adhere to the Hierarchy of Controls to prioritize interventions.
Collaborate with the team for in-depth discussions on mitigating risks connected with root causes.

Practical Examples

Case: Scratches in Punches
- Identify issues like inadequate inspection and maintenance that lead to wear and tear.
- Establish that operator oversights contributed to operating beyond defined limits.
Case: Ineffective Adhesives
- Examine factors like inadequate compaction parameters and excessive speed in machinery operation.
- Identify training and communication gaps among operators as significant contributors.

Continuous Improvement

Use Countermeasure Tracker to assess the effectiveness and sustainability of implemented solutions.
Emphasize lessons learned from problem-solving efforts to foster a culture of continuous improvement.
