Fishbone diagrams are best suited to short phrases or simple ideas—they can get cluttered and confusing easily.

Depending on the situation you’re investigating or your business model, these categories may fit perfectly or they may not resonate. Feel free to edit the categories as needed for your business, but be careful not to exclude anything that may have contributed to your issue. It helps you group all the potential causes of a problem in a structured way to find the ultimate cause of your problem. Kaoru Ishikawa invented this diagram in the 1960s to use as a quality control tool at the University of Tokyo.
