As organizations strive to expand system capabilities through the development of system-of systems SoS architectures, they want to know "how much effort" and "how long" to implement the SoS. In order to answer these questions, it is important to first understand the types of activities performed in SoS architecture development and integration and how these vary across different SoS implementations. This article provides results of research conducted to determine types of SoS lead system integrator LSI activities and how these differ from the more traditional system engineering activities described in Electronic Industries Alliance EIA 632 "Processes for Engineering a System". This research further analyzed effort and schedule issues on "very large" SoS programs to more clearly identify and profile the types of activities performed by the typical LSI and to determine organizational characteristics that significantly impact overall success and productivity of the LSI effort. The results of this effort have been captured in a reduced-parameter version of the constructive SoS integration cost model COSOSIMO that estimates LSI SoS engineering SoSE effort.
