Wikipedia

Requirements engineering

Requirements engineering (RE) is the process of defining, documenting, and maintaining requirements in the engineering design process. It is a common role in systems engineering and software engineering.

The first use of the term requirements engineering was probably in 1964 in the conference paper "Maintenance, Maintainability, and System Requirements Engineering", but it did not come into general use until the late 1990s with the publication of an IEEE Computer Society tutorial in March 1997 and the establishment of a conference series on requirements engineering that has evolved into the International Requirements Engineering Conference.

In the waterfall model, requirements engineering is presented as the first phase of the development process. Later development methods, including the Rational Unified Process (RUP) for software, assume that requirements engineering continues through a system's lifetime.

Requirements management, which is a sub-function of Systems Engineering practices, is also indexed in the International Council on Systems Engineering (INCOSE) manuals.

Examples of use of performance requirements

1. A Honda representative said the company supported fuel economy increases through performance requirements.

2. "The Army may be learning that its performance requirements are so demanding that adapting commercial helicopters is almost as hard as starting from scratch on a new military design," Thompson said.

3. "The program is being loaded up with more performance requirements than is prudent," he said, noting that any reduction in the amount of equipment that needs to go aboard the helicopter could favor the Sikorsky bid.

4. Whereas the Army has been ridiculed for decades for overspending on aircraft, it now faces questions of whether it was too cost–conscious. The Army may be learning that its performance requirements are so demanding that adapting commercial helicopters is almost as hard as starting from scratch on a new military design,‘‘ Thompson said.

5. Test images from the third camera of the science payload were released March 24. (See related article.) "The test images show that both cameras will meet or exceed their performance requirements once they‘re in the low–altitude science orbit," said Michael Malin, team leader for the Context Camera and principal investigator for the Mars Color Imager.
