This textbook is about three key aspects of system design: decision making under uncertainty, trade-off studies and formal risk analyses. Recognizing that the mathematical treatment of these topics is similar, the authors generalize existing mathematical techniques to cover all three areas....

Usability flaws found in the later stages of the development process can be extremely costly to resolve. Accordingly, usability evaluation (UE) is an important, albeit expensive, part of software development. We report on how the inexpensive usability evaluation method of heuristic evaluation...

The need for tools and meeting methods to provide effective support during data model development meetings has been an elusive goal. Researchers at the University of Arizona have developed collaborative tools and methods to support groups during these meetings. This paper discusses meeting...

This paper extends previous research by proposing a model that can help explain ways to motivate member contributions to online communities (OCs). New features in the model will allow researchers to test the relative effects of extrinsic and intrinsic rewards as motivators in OCs. Some OCs have...

The use of software products in today’s world has increased dramatically making quality an important aspect of software development. There is a continuous need to develop processes to control and increase software quality. Software code inspection is one way to pursue this goal. This paper...

During business analysis, business activities are modeled and analyzed. Redefined models become the blueprints for improved business activities. The cost to produce models of the organization is high and model accuracy is important. Involvement from knowledgeable participants and stakeholders is...
