Industrial engineering tool for failure analysis: Fishbone diagram and FMEA — Lesson 3

This lesson covers the subject of failure analysis and prevention, focusing on the application of industrial engineering tools. It discusses the use of the Pareto diagram to identify vital factors affecting product or process performance. The lesson also introduces the Fishbone or Ishikawa diagram, a qualitative tool that uses a team-based approach to identify major and minor causes related to failure. The lesson further delves into the Failure Mode and Effect Analysis (FMEA), a preventive technique that helps identify potential failure modes in a system, their causes, and effects. For instance, it explains how FMEA can be used to prioritize risks associated with various components in a system.
