The fishbone shape is due to angling of lines so text can more easily be fitted in. Its main use is to discover potential causes of unwanted problems. It also can be used more flexibly for such as discovering how to cause solutions. The main 'bones' of the fishbone diagram typically are the 'four Ms' as below. Sometimes two more Ms are added: 'Mother Nature' (the environment) and 'Measurements'. The four Ms are also sometimes changed to the four Ps: People (manpower), Process (methods), Plant (machines) and Products (materials).
