Create a fishbone diagram of any major problem you can research

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.
