| Constructive Cost Model

Software Intensive Systems-of-Systems

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), prine 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.
