Existing algorithmic models fail to produce accurate software development effort estimates. To address this problem, a case-based reasoning model, called Estor, was developed based on the verbal protocols of a human expert solving a set of estimation problems. Estor was then presented with 15 software effort estimation tasks. The estimates of Estor were(More)
An exploratory study was conducted (a) to examine whether experieticed software managers could generate accurate estimates of effort required for proposed software projects and (b) to document the strategies they bring to bear in their estimations.

Popular lore tells us that genius is born, not made. Scientific research, on the other hand, reveals that true expertise is mainly the product of years of intense practice and dedicated coaching. Ordinary practice is not enough: To reach elite levels of performance, you need to constantly push yourself beyond your abilities and comfort level. Such(More)
Since 2001, many state and local health departments have implemented automated systems to monitor healthcare use and to promptly identify and track epidemics and other public health threats. In 2007-08, we conducted case studies of selected events with actual or potential public health impacts to determine whether and how health departments and hospitals(More)
Negotiation between two individuals is a common task that typically involves two goals: maximize individual outcomes and obtain an agreement. However, research on the simplest negotiation tasks demonstrates that although naive subjects can be induced to improve their performance, they are often no more likely to achieve fully optimal solutions. The present(More)
Open source software is booming. Once the domain of hobbyists and hackers, it has gained acceptance with consumers, corporations, and governments. Some exemplars of open source, such as the Linux and Android operating systems, are now commonplace, operating millions of devices. Together with other products of open source software, they have been creating(More)
