Quality checkpoints and quality control points- Introduction
Western managers are now aware of the importance of establishing a measuring system which includes measurements from the process (management as well as production processes) which enable the results and also measurements of the results. it is important that management and the employees in the various firms and processes take the time needed to determine whether the examples shown here can be used or whether there are alternative possibilities for both quality checkpoints and quality control points.
