The paper aims at presenting a method of controlling software quality attributes driven by the set of requirements. This is done in three steps: specifying all the requirements, mapping them to quality attributes and controlling the development process against the demanded quality. The steps adapt and integrate well-known patterns of requirements specification and weighting, evaluation of the software demanded quality, and measuring the development process. A supporting prototype tool and the related example of a distributed application assist in presentation of requirements specification and their mapping to quality characteristics, while the latter step is discussed in draft. Some further research problems and questions are shown. key words: requirements specification, software quality control, quality tree model, QFD method, GQM approach
