To obtain the proper base of Shingo�s work, we must adopt the Japanese mind set of manufacturing which differs (Thank GOD) from Frederick W. Taylor.
Japanese view manufacturing as a network consisting of two interrelated structures.
The Process Structure: the flow by which raw materials are converted into finished goods. Within the process structure, there are four categories to which a process goes through.
The Operation Structure: the actions performed on materials. Three categories can be occurring within the operation structure. Preparation and After Preparation adjustments, Principal Operations, Marginal Allowances.
Process vs. Operation
Manufacturing is a network of two structures. Problems Occur When They Disagree!
