The SEI is currently conducting research in the area of quality attribute analysis.
Software-reliant systems depend not only on achieving acceptable functionality, they also depend on non-functional properties, which may include security, reliability, interoperability, openness, or agility. When these non-functional properties, or quality attributes, are not addressed sufficiently early in the system-development or evolution life cycle, unacceptable system behavior and delays in fielding can result.
SEI research focuses on the structure and behavior of software-reliant systems and the relationship between structure and quality attributes. Our approach uses a combination of formal notations, quantitative analyses, and qualitative methods to address conflicts among quality attributes that may arise at any phase of system development. The SEI’s work provides foundations for handling multiple critical quality attributes in both dynamic and resource-constrained environments.
Our approach recognizes that systems of increasingly large scale will
