Show these possible causes as shorter lines coming off the "bones" of the diagram. Where a cause is large or complex, then it may be best to break it down into sub-causes.

For each of the factors he identified in step 2, the manager Case study fishbone diagrams possible causes of the problem, and adds these to his diagram, as shown in figure 3.
Analyze Your Diagram By this stage you should have a diagram showing all of the possible causes of the problem that you can think of. Depending on the complexity and importance of the problem, you can now investigate the most likely causes further.
This may involve setting up investigations, carrying out surveys, and so on. These will be designed to test which of these possible causes is actually contributing to the problem.

This helps you to carry out a thorough analysis of the situation. There are four steps to using the tool. Work out the major factors involved.
You'll find this method is particularly useful when you're trying to solve complicated problems.
