Combining strategy and deliberation in the requirements engineering process

Methods for requirements engineering are in abundance. They fall into two broad categories. Those that advocate a prescriptive stance and those that reject a methodical approach by adopting a descriptive stance. Of course no `silver bullet´ has been found in the way of working within the discipline of requirements engineering. We argue that each of the two paradigms can make a significant contribution towards improving the requirements engineering process and we show how the two models can successfully co-exist in practical situations. This co-existence facilitates, within a single framework, the search for strategy and deliberation, two aspects of requirements engineering that we regard as being of critical importance for successful systems development
