However, for short run processes, it is necessary to find a substitute for this information to set up process control parameters until a sufficient volume of parts is produced to calculate them directly from the process. The purpose of the *[SPC Short Run Supplement](http://www.aiag.org/products/products-list/product-details?ProductCode=XO-CQI-26) *is to provide an approach with examples to short run SPC. Through discussion of the fundamental tools and advocacy of a back-to-basics approach, this guideline presents the subject matter in a straightforward manner to benefit a majority of applications. This guideline is not intended to supplant the *[SPC Reference Manual](http://www.aiag.org/products/products-list/product-details?ProductCode=SPC-3) *but to supplement and simplify its contents when a short run application is called for. AIAG has also recently published has the [*CQI-25 SPC Quick Start Guide*](http://www.aiag.org/source/orders/prodDetail.cfm?productDetail=CQI-25). This guideline is perfect for those looking for an introduction to SPC or people who have limited experience with SPC. The [*CQI-25 SPC Quick Start Guide*](http://www.aiag.org/products/products-list/product-details?ProductCode=CQI-25) covers about 90% of the applications in the full SPC Core Tool reference manual. AIAG created this guideline so that suppliers could quickly find the answers to their SPC-related questions. It focuses on key information from the SPC reference manual and designates levels of importance for different methodologies. To order the new [CQI-26](http://www.aiag.org/products/products-list/product-details?ProductCode=XO-CQI-26) or the [CQI-25](http://www.aiag.org/products/products-list/product-details?ProductCode=CQI-25), visit www.aiag.org or contact AIAG customer service for help at (248) 358-3003.
