Requirements based system level risk modeling
The problem that we address in this paper is assessing the expected degree of success of the system or mission based on the degree to which each requirement is satisfied and the relative weight of the requirements.

Matching software practitioner needs to researcher activities
We present an approach to matching software practitioners' needs to software researchers' activities. It uses an accepted taxonomical software classfication scheme as intermediary, in terms of which practitioners express needs, and researchers express activities.

Using dissimilarity metrics to identify interesting designs
We report on application of a combination of data mining steps guided by user-directives, and appropriate visualizations to present the results of these steps to the users.

Relating practitioner needs to research activities
We present an approach to matching needs (practioner requirements) to solutions (researcher activities). A taxonomical classification scheme acts as intermediary between needs and activities. Expert practitioners exprss their needs in terms of this taxonomy. Researchers express their activities in the same terms. A decision support tool is used to assist in the combination and study of their expressions of needs and activities.

Software support for improving technology infusion
This paper focuses on describing the custom software tool, DDP, that was developed to support the TIMA process, and on showing how the needs of the TIMA process have influenced the development of the structure and capabilities of the DDP software.

Requirements, architectures and risks
We advocate the use of risk-based reasoning to help make good architectural decisions. We explore the adaptation of a risk management process and tool to this purpose.
