M30 - Fishbone Diagram: Improving an Improvement Tool

Monday, April 30
3:00 PM - 4:00 PM
Location: WSCC Ballroom 6A

Level: Basic

The Ishikawa fishbone diagram is a globally recognized problem-solving tool. It's one of the seven basic quality tools and a standard in Six Sigma methods. The fishbone diagram is used to explain the cause and effect relationships within a problem. A thorough and accurate explanation of anything—why the tides change, why a part has a defect, why a project deadline was missed and why you spilled your coffee—is the collection and organization of cause and effect relationships. Cause and effect is a principle. It's fundamental. It doesn't change. The elements within the fishbone are sound, but there is considerable variation in how the tool is applied. The fishbone is a process, and like any process, it can be improved.
