A Market-driven Requirements Engineering Process - Results from an Industrial Improvement Programme

In market-driven software evolution, the objectives of a requirements engineering process include the envisioning and fostering of new requirements on existing packaged software products in a way that ensures competitiveness in the market place. This paper describes an industrial, market-driven requirements engineering process which incorporates continuous requirements elicitation and prioritisation together with expert cost estimation as a basis for release planning. The company has gained a measurable improvement in delivery precision and product quality of their packaged software. The described process will act as a baseline against which new promising techniques can be evaluated in the continuation of the improvement programme.
