Cause & Effect Diagram
  • The Cause and effect diagram is also called:
    • Fishbone Diagram-because of the way it looks
    • Ishakawa Diagram for the inventor, Dr. Kaoru Ishakawa.

Root Cause

What is a Cause and Effect Diagram?
  • A visual tool to identify, explore and graphically display, in increasing detail, all of the suspected possible causes related to a problem or condition to discover its root causes.
  • Not a quantitative tool
why use cause effect diagrams
Why Use Cause & Effect Diagrams?
  • Focuses team on the content of the problem
  • Creates a snapshot of the collective knowledge of team
  • Creates consensus of the causes of a problem
  • Builds support for resulting solutions
  • Focuses the team on causes not symptoms
  • To discover the most probable causes for further analysis
  • To visualize possible relationships between causes for any problem current or future
  • To pinpoint conditions causing customer complaints, process errors or non-conforming products
  • To provide focus for discussion

physical c e construction
Physical C&E Construction
  • C&E Fishbone diagrams can be constructed two ways:
  • Paper and pen
    • Usually more effective when working in a team
    • May take multiple sheets of flip chart paper
    • Many teams find it helpful to do the flip chart method first because it lends itself to group dynamics. Everyone can see and participate easier.
  • Minitab software
    • Very helpful when sharing diagram with an audience outside of your team
c e workshop
C&EWorkshop

In Project Teams, complete the following items:

1. Determine the problem or “head’ of the fishbone

2. Determine if your process is Transactional/Commercial or Product/Industrial

3. Create a Cause & Effect (C&E) Fishbone diagram using:

- 4 P’s and M & E (Transactional process)*

- 5 M’s and E (Product process)*

* Use the headings (Ps and Ms) as guidelines. Customize to better describe the process
