Cause and effect diagram; fishbone diagram. A problem-solving graphic. The problem is written on the right hand side of a sheet. A "fishbone" of lines is drawn towards the problem statement, and labelled with groups of potential causes e.g. 6M (Man, Materials, Machines, Measurements, Mother Nature) or 4P (People, Processes, Policies, Procedures). Individual potentials causes are then added to the fishbone, for example by brainstorming.
