In every realization of the production process certain input materials (raw materials, energy, information), management (adjustment, checking, inspection) and necessary resources (equipment, machines, computers) are included in order to obtain production results. Process results can be necessary for processed materials, finished products, management software, and useful service. The obtained results of the process go through a control process that determines: nonconformity, defect, correction, rework, repair and scrap. Usually, a good production process with a high percentage of correctness, a low percentage of corrections, and a minimum percentage of wrong process results are planned. How to get a good production process? A good production process must have a certain dependency, the necessary precision, the necessary accuracy, the desired economy, and the minimum duration. In this paper, we show how the bad process can be repaired to become a good production process.
