case study on the demonstration of capability to manufacturing process

There are two factors that reduce the opportunity for certification process as capable. The first factor is the volume of production and the second factor is related to the level of precision required by the client runtime, ie the size tolerances. The tolerance is low, the capability value decreases and the process must be improved to meet the minimum capability values. Both aspects of production volumes and related capabilities accuracy (precision and accuracy of the estimate process capability) are combined in a calculation of economic efficiency, it finally generates design quality system.
