Cause and Effect Tool in Six Sigma
Cause and Effect (Fishbone) Diagram
A cause and effect diagram, also known as a "fishbone" diagram, can help in brainstorming to identify possible causes of a problem and in sorting ideas into useful categories, which is a common tool using in six sigma programs for root cause analysis. The fishbone will help to visually display the many potential causes for a specific problem or effect. It's particularly useful when capturing different ideas when there are many opinions in root cause identification.
Fishbone Suggested Categories
- 6 Ms: Machine, Method, Material, Man Power, Measurement, Mother Nature (Environment).
- 7 Ps: Product, Price, Place, Promotion, People, Positioning, Packaging
- 5 Ss: Surroundings, Suppliers, Systems, Skills, Safety
How to Create Cause-Effect Diagram For Six Sigma Initiative
Step 1: First you need to state a problem. Be as clear and specific as you can about the problem. This is written at the mouth of the "fish."
Step 2: Identify major categories of causes of the problem. They are branches extended from the trunk. (Refer to suggested categories of the upper part.)
Step 3: Brainstorm all causes of the problem, collect all opinions and add them to appropriate categories. Causes can be written in more than one places.
Step 4: Write sub causes branching of the branches. Continue to ask "Why?" and generate deeper levels of causes.
