UNDERSTANDING THE PROBLEM
Fishbone diagram, also known as a cause and effect diagram, aims to help us identify the possible causes of an event, outcome or issue. To help us consider the issue from different perspectives the diagram breaks down the potential causes into the following categories: equipment, process, people, materials, environment and management.
