The SPC Short Run Supplement (CQI-26) guideline was developed to address the particular uniqueness of short run production, where suppliers do not have the production volume to readily apply the approaches identified in the SPC Reference Manual, 2nd Edition. Providing easy to understand examples of commonly used short run charts, the SPC Short Run Supplement is a guideline used to analyze, monitor and control process that do not satisfy the sampling requirements of standard SPC charts. This document is not intended to supplant the SPC Reference Manual but to supplement and simplify its contents when a short run application is called for.
