The software development process often encounters obstacles to reuse analysis patterns. Many designers do not have access to these computational artifacts by the difficulty in finding them, since the ways in which analysis patterns are documented are often precarious. The lack of both a computational tool which supports the analysis patterns documentation process and a digital repository to sto...

We have been developing Quality Objects (QuO), an adaptive middleware framework that supports the development of distributed object applications that can measure, control, and adapt to quality of service (QoS) needs and variations in a system. We have applied QuO to the problems of distributed real-time embedded (DRE) applications, including a streaming video dissemination application and a dyn...

Software architecture (SA) evaluation is a quality assurance technique that is increasingly attracting significant research and commercial interests. A number of SA evaluation methods have been developed. Most of these methods are scenario-based, which relies on the quality of the scenarios used for the evaluation. Most of the existing techniques for developing scenarios use stakeholders and re...

Advocates of software design patterns claim that using design patterns improves communication between software developers. The controlled experiment that we describe in this report tests the hypotheses that software maintainers of well-structured, well-documented software containing design patterns can make changes (1) faster and (2) with less errors if the use of patterns is explicitly documen...
