BUILDING SYSTEMS FROM COMMERCIAL COMPONENTS

A principal source of risk in component-based software design, say Wallnau and two other technicians at the institute, Scott A. Hissam and Robert C. Seacord, is a lack of knowledge about how components should be integrated and how they behave when integrated. To mitigate that risk, they introduce several concepts, among them the component ensemble as a design abstraction, blackboards as a fundamental design notation, and a process for exposing design risk. They speak to practicing and student software engineers.
