The application of specific instructions and regulations are needed to meet customer demands. The production of faulty products is the biggest source of danger and loss for factories and also for end-customers. The reduction of deficiency number is the task of quality management. Continuous development, feedback, intervention and efficient actions are needed to minimize the number of faulty machines. This article is an overall introduction to quality techniques used at production processes. The aim of this work is to point out how difficult the product realization process is and the handling of possible production problems after serial production. The most efficient tool of this is the successful 8D-method. The introduction of the 8D-method is the basis of our work.
