When dealing with quality requirements, you often end up in difficult trade-off analysis. You must take into account aspects such as release targets, end-user experience, and business opportunities. At the same time, you must consider what is feasible with the evolving system architecture and the available development resources. Our experience from the mobile-phone domain shows that much can be gained if development team members share a common framework of quality indicators and have a simple, easy-to-use model for reasoning about quality targets. To support quality-requirements analysis, the Quper (quality performance) model combines cost and benefit views into a roadmap of each important quality indicator for the particular domain. The practical application of Quper involves six steps. This article is part of a special issue on quality requirements.
