Observations on the Measurement of Systems Engineering Capability

In the past few years, several models have been developed to measure systems engineering process maturity. Two of these models have gained a great deal of attention: the INCOSE SECAM and the EPIC (formerly Industrial Collaboration) SE-CMM. This paper describes the conduct of a dual systems engineering process assessment that applied both of these well known models to the same organization using the EPIC SE-CMM Appraisal Method, rather than the shorter duration INCOSE SECAM Assessment Method. The assessment was conducted at Hughes Aircraft Company (HAC), Electro-Optical Systems (EOS). The assessment is noteworthy since it is the first time both models have been applied concurrently. This paper provides a synopsis of both models along with a description of the dual assessment. Issues observed from the assessment regarding the models and the Appraisal Method are described; their resolution is important for the conduct of future assessments. Impacts upon the two models and application methods are discussed based upon the experiences gained from the dual assessment.
