Requirements Management

The requirements book ensures the “balance of systems” . It is based on the draft space and allocation programme and the definition of those quality standards that were determined in interviews and hearings with users. One of the major challenges is to cope with often competing and contradictory requirements of different stakeholders. An analysis or mediation process, involving all stakeholders as well as authorities can help solve the problem. This will lead to the most efficient solution because it integrates all relevant aspects.
