Constructive Cost Model for
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), 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.
