Abstract. Past analysis has shown that there is a quantifiable correlation between the amount, types and quality of systems engineering efforts used during a program and the ess of the program. For any given program, an amount, type and quality of systems engineering effort can be selected from the quantified correlations. The optimal nature of these selections, however, has not yet been explored. An ongoing project, Systems Engineering Return on Investment (SE-ROI), aims to quantify the correlations by gathering data on current pleted programs. As a first step in that quantification, the project has proposed an ontology of systems engineering that can provide useful correlations. This ontology is based on a review of current systems engineering standards, historical systems engineering activities, and data gathered on the COSYSMO and Value of Systems Engineering projects. Further analysis is ongoing on the definitions of terms such as "systems engineering effort," "amount," "type," "quality," "ess," and "optimum." Through this analysis and subsequent data gathering, the SE-ROI project will yield more specific relationships between systems engineering activities, such as requirements management effort, and the cost/pliance of the program.
Background
The discipline of systems engineering (SE) has been recognized for 50 years as essential to the development plex systems. Since its recognition in the 1950s [Goode 1957], SE has been applied to products as varied as ships, computers and software, aircraft, environmental control, urban infrastructure and automobiles [SE Applications TC 2000]. Systems engineers have been the recognized
