The 4M What is 4M man Method Machine material? 4M categories (Material, Method, Machine, Man) are often used in the Cause-Effect Diagram created by Kaoru Ishikawa [9]. It is a good, intermediate tool of problem analysis. By the use of these methods it could be analyse any production, service or management problem. xIU9viQ.
