Application of a broad-spectrum quantitative requirements model to early-lifecycle decision making

چکیده
During the early phases of projects’ lifecycles, detailed information is scarce; yet there is frequent need to make key decisions, especially those concerning tradeoffs among quality requirements. Trading among competing concerns occurs in many fields, e.g. systems engineering, hardware engineering, and software engineering. Here, we report on our design and use of a model to help make requirements decisions that applies to all of these fields. To do so, we employ a model based upon coarse quantification of the factors involved. We illustrate our approach with fragments taken from some of our studies of software technologies.
