Introducing Support for Release Planning of Quality Requirements — An Industrial Evaluation of the QUPER Model

Abstract

In market-driven product development and release planning, it is important to market success to find the right balance among competing quality requirements. To address this issue, a conceptual model that incorporates quality as a dimension in addition to the cost and value dimensions used in prioritisation approaches for functional requirements has been developed. In this paper, we present an industrial evaluation of the model. The results indicate that the quality performance model provides helpful information about quality requirements in release planning. All subjects stated that the most difficult estimations may be more accurate by using the quality performance model.
