Gives ways of applying regular variables control charts to short runs and small mixed batches where the sample size for monitoring is restricted to one and also provides a set of tools to facilitate the understanding of sources of variation in such processes so that the processes can be better managed.

This document describes ways of applying regular variables control charts to short runs and small mixed batches where the sample size for monitoring is restricted to one. It provides a set of tools to facilitate the understanding of sources of variation in such processes so that the processes can be better managed.

The charts described are process-focused rather than product-focused. The user can plot, monitor and control similar characteristics on different items, or different characteristics on an item, on a single control chart.

NOTE1 The terms short run and small batch size are not well defined. Here, short run and small batch size are taken to mean only a few items are manufactured before a different item is then produced.

NOTE2 For situations where the subgroup size is larger than one, other standards apply.
