Large software companies have to plan their project portfolio to maximize potential portfolio return and strategic alignment, while balancing various preferences, and considering limited resources. Project portfolio managers need methods and tools to find a good solution for complex project portfolios and multiobjective target criteria efficiently. However, software project portfolios are chall...

Statistical analysis is greatly hindered with missing information. It represents a loss of key data, but worse, it can introduce biased results in the analysis. A way to rectify the problem of missing data is to employ a sound method of imputation, a way to replace missing values with reasonable estimates. Their exists variety of estimation models like SLIM, COCOMO and other models like machine...

In his New Science,1 Giambattista Vico provided us with four axioms, which if followed, could help prevent us from falsifying our knowledge of history and our understanding of ourselves.2 Although all four axioms are relevant, the last two-"the conceit of nations" and "the conceit of scholars"-are particularly important as reminders to American legal scholars who all too often fall prey to the ...

This presentation summarizes the results of experiments conducted over the past year to empirically validate extensions made in an attempt to use the COCOMO II Early Design model to accurately estimate web development effort and duration. The presentation starts by summarizing the challenges associated with estimating resources for web-based developments. Next, it describes a new sizing metric,...

Accurate estimates are essential to the proper management of software development projects; many software estimates have very wide bounds between the lower and upper estimates of effort. The width of estimates bounds is determined by the degree of uncertainty in the available data. One of these sources of uncertainty is the use of previous projects; especially where those projects do not exhibi...
