This document is an overview of the SASIG ECM Reference Process. The purpose of this document is to further elaborate on and cover topics not specifically addressed by the SASIG ECM Recommendation. The SASIG ECM WG feels that additional simplification will help the end users better understand the strategy and thought process behind the SASIG ECM Recommendation.

The SASIG ECM Reference Process (in IDEF0 notation) covered in this documents reflects the collective, consensus based position taken by the global SASIG Work Group on the said Reference Process and all it’s sub-process on level 1 e.g. Engineering Change Request (ECR) and Engineering Change Order (ECO). Details and special cases (back jumps and iterations) are not shown intentionally because all such details are covered in the SASIG ECM Recommendation.

This IDEF0 notation is not a substitute to the detailed ECM Reference Process outlined in The SASIG ECM Recommendation, which is the Master Document.

The term “Reference Process” is used to emphasize the fact that the ECM Process here is not intended to reflect any in-house ECM Process of any contributing member companies.
