Estimating the costs of software development is one of the most important activities in software project management. Inaccuracies in such estimates may cause irreparable loss. A low estimate of the cost of projects will result in failure on delivery on time and indicates the inefficiency of the software development team. On the other hand, high estimates of resources and costs for a project wil...

Our purpose in this article is to combine three previously published papers in order to apply a general Methodological frame to a specific problem. Because system design is a special case of problem solving, we will try to apply A Generalized Group Decision Support System (GDSS) for Group Problem Solving: (Callaos, et.al. 1999; Callaos and Lesso, 1999) to the specific area of System Design. Thi...

In previous work, we showed that the critical engagement with a decision support system during its implementation by a project team is an important antecedent for the successful later use of the technology. However, the mechanisms that trigger such critical engagement are so far not well understood. Drawing on Heidegger’s modes of Being-in-the-world this paper provides a theoretical frame to un...

IntroductIon Finding appropriate decision support systems (DSS) development processes and methodologies is a topic that has kept researchers in the decision support community busy for the past three decades at least.

This paper reviews the problems, approaches and analytical models on project control systems and discusses the possible research extensions. The discussion could help to identify open problems and research areas with wide practical applications which require further research. Furthermore, the conclusions summarized might serve as a useful base for developing decision support systems (DSS) that ...

Decision support is a crucial function for decision makers in many industries. Typically, decision support systems help decision-makers to gather and interpret information and build a foundation for decision-making. Medical Decision Support Systems (DSS) play an increasingly important role in medical practice. By assisting physicians with making clinical decisions, DSS are expected to improve t...
