The discipline of systems engineering continues to increase in importance. There are more projects, projects are larger, and projects are more critical, and all of these mean that more and better systems engineering is required. It follows that the cost of systems engineering continues to increase in importance. In turn, it follows that accurate estimation of systems engineering costs continues to increase in importance, as systems engineering results suffer if a project either underestimates or overestimates its cost.
There are models for estimating systems engineering cost, notably COSYSMO 1.0, but all these models leave out some aspect of modern practices, and therefore tend to estimate a modern systems engineering cost inaccurately, or not at all. These modern practices include reuse of engineering artifacts, requirements volatility, and engineering in a system-of-systems context. While all of these practices have been addressed to some extent in research papers, there is no all-encompassing model that integrates all of them.
My research has resulted in an integrated model that includes the features of COSYSMO 1.0 and covers those modern practices. It is open and therefore widely available. I have completed a comprehensive model based, in part, on actual project data.
