Questions

What is a fishbone diagram?

An Ishikawa or cause-and-effect diagram: the problem at the head and its possible causes grouped on bones.

What are the 6M, 8P and 4S categories?

Standard category sets: 6M for manufacturing, 8P for services and 4S for the service industry. Rename any bone.

How many causes fit?

Up to 8 categories, 6 causes on each bone and 3 sub-causes per cause. Bones grow to fit.

Is this the lab value fishbone?

No. For BMP, CBC and other lab skeletons, use the Lab Fishbone tool instead.
