This is an example of a fishbone diagram. A fishbone diagram is a technique for visualizing and classifying the sources of an issue. This technique is used to determine the root causes of an issue. A fishbone diagram, which is commonly used for root cause analysis, combines the concept of brainstorming with a form of mind map template. As a test case approach for determining cause and effect, it should be effective. Please feel free to modify this template and use it to construct your own diagram in EdrawMax.
