EIA/IS-731: Systems Engineering Capability Model


From SEI: CMMI Models FAQ:

EIA 731, the Systems Engineering Capability Model, is a source document for CMMI. A mapping that compares EIA 731 and CMMI v1.1 is available on the SEI Web site, including a mapping from CMMI v1.1 to EIA 731 at http://www.sei.cmu.edu/cmmi/casestudies/mappings/cmmimappings.cfm, from EIA 731 to CMMI v1.1 available at http://www.sei.cmu.edu/cmmi/casestudies/mappings/cmmimappings.cfm, and a document to help you interpret these mappings at http://www.sei.cmu.edu/cmmi/casestudies/mappings/cmmimappings.cfm. An article that discusses Transitioning from EIA/IS 731 to CMMI is also available at

ITAA EIA-731-1 was formerly EIA/IS 731.1.

ANSI/EIA 632 - Processes for Engineering a System

EIA 632 came about because the U.S. Department of Defense (DoD) determined in 1994 that MIL-STD-499B would not be released as a military standard. EIA's Committee on Systems Engineering (the "EIA G-47 Committee") agreed to undertake the task of "demilitarizing" 499B and releasing it as an industry standard. The intent was to revise the MIL (military) version in accordance with commercial practices in order to broaden the suitability of the standard for other government agencies and commercial industry. EIA632 provides a comprehensive, structured, disciplined approach for all life cycle phases. The systems engineering process is applied iteratively throughout the system life cycle. Key aspects of industry's initiatives are captured to better identify and integrate requirements and implement multi-disciplinary teamwork, including potential suppliers, early in establishing the requirements. Other key aspects include establishing clear measurements of system responsiveness, encouraging innovation in products and practices, and focusing on process control rather than inspection. Also, risk management is encouraged.
