What is a Fishbone (Ishikawa) diagram?

Find the root cause of a problem with an Ishikawa diagram section.

The Fishbone diagram (or Ishikawa diagram) is a popular problem-solving tool that allows users to get to the root cause of an issue by listing all possible causes and narrowing down from there.

The ‘head’ of the fish is where you write the problem, and the ‘bones’ of the fish are where you will identify the categories and the causes.
