The EIA G-47 Committee initiated an effort to merge the INCOSE System Engineering Capability Assessment Model (SECAM) and the EPIC SE-CMM in 1996. EIA Interim Standard (IS) 731, Version 1.0 was released on January 20, 1998. It contained two parts: Part 1 was the Systems Engineering Capability Model (SECM) and Part 2 was the SECM Appraisal Method. The purpose of this standard is to support the development and improvement of system engineering. Attention to this standard has become overcome by events (OBE) because of the Integrated Capability Maturity Model (CMMI) initiative, being driven by the U.S. DoD, and being worked by the NDIA by representatives of the EIA and the SEI.
