Constructive Cost Model for

Software Intensive Systems-of-Systems

 

Lead Personnel: Jo Ann Lane

Objectives

Today's need for more complex, more capable systems in a short timeframe is leading more organizations towards the integration of existing systems into network-centric, knowledge-based system-of-systems (SoS). Software and system cost model tools to date have focused on the software and system development activities of a single software system. As we view the new system-of-systems architectures, we find that the System of Systems Engineering (SoSE) effort (often performed by a Lead System Integrator (LSI), prime contractor, government team) associated with the definition of the overall SoS architecture and then the integration of these system-components is not handled well, if at all, in current cost models. Efforts are currently underway to better understand SoSE effort and to use this information to develop a cost model, COSOSIMO, to estimate this effort.
