5 Whys root cause analysis

This module introduces the 5 Whys methodology for root cause analysis, emphasizing its simplicity and effectiveness in identifying underlying problems. It proposes how repeatedly asking "why" can uncover both specific and systemic root causes, illustrated with real-world examples like a famous Memorial monument case study and semiconductor industry case studies. The module highlights the importance of teamwork and clear problem statements, while also noting limitations such as potential for oversimplification and lack of repeatability. The 5 Whys method is positioned as a foundational tool, often used within broader methodologies for comprehensive problem-solving in manufacturing.
