Ishikawa Fishbone Diagram Types
There are many ways to use the Ishikawa diagram. You can analyze root causes using the classic format, step-by-step format, or a custom format. An Ishikawa or fishbone diagram always contains:
- The head of the fish (problem statement)
- One or more major "bones" or causes
- A series of smaller "bones" coming off the main bones to show the "Five Whys" used to identify the cause-effects.
