Observations on the Measurement of Systems Engineering Capability

Abstract

AbstractIn 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.
