Reuse in systems engineering is a frequent, but poorly understood phenomenon. Nevertheless, it has a significant impact on estimating the appropriate amount of systems engineering effort with models like the Constructive Systems Engineering Cost Model. Practical experience showed that the initial version of COSYSMO, a model based on a " build from the(More)
The objective of this paper is to examine the gaps and overlaps between software engineering and systems engineering cost models with intent to harmonize the estimates in engineering estimation. In particular, we evaluate the central assumptions of the COSYSMO and COCOMO II models and propose an approach to identify gaps and overlaps between them. We(More)
As the industry undergoes a paradigm shift from a system-based procurement model to a capability-based acquisition model with a focus on integration of legacy systems and interoperability of systems of systems and families of systems, new challenges have emerged for the field of cost estimating. What is the cost of an operational capability in a net centric(More)
