Research work continues into Systems Engineering Return on Investment (SE-ROI)rnfollowing prior work on Value of Systems Engineering and Systems Engineering Effectiveness.rnIn the current work, 1.5-hour interviews are being held with the leaders of completed systemrndevelopment programs to obtain extensive data on systems engineering activities, programrnsuccess measures, and possible correlative parameters. The resulting information is beingrnexamined statistical to determine empirical knowledge about the return on investment of systemsrnengineering activities. As of this writing, interesting results in the demographics have beenrnobserved based on 30 program interviews. This paper provides information showing (a) sourcerninformation on the interviewed programs, (b) observed quantitative breakdown of systemsrnengineering effort into eight activities, (c) histogram spreads of the observed characteristics of thernsource programs, and (d) histogram spreads of the observed correlative parameters. The paperrnalso provides initial indications of the differences between successful and unsuccessful programs.
