Abstract
Many companies feel they cannot utilize statistical process control (SPC) charts because their average product run length is too short. This situation leads statisticians and quality managers to develop, encourage to use and apply statistical tools for short production runs. In Poland these SPC tools are not so popular, especially in small companies. It is a result of very low awareness of existing such methods or distrust to using statistical methods in case of short production runs. Because usage of SPC methods is sometimes a requirement for subcontractors from the side of big clients, Polish companies are not as competitive as foreign companies more frequently using SPC tools for short production runs.
The purpose of this article is to describe the control charts (e.g. difference-from-nominal) and indices for providing statistical control of a short-run process.
A case from Polish machining industry is presented.
