: Business-IT alignment for software specifications means that the specifications have to be aligned with business goals. In the SIKOSA research project, we developed the SIKOSA methodology which supports the integrated assurance of quality during the whole software development process. In the present work, we present these aspects of the SIKOSA methodology, which especially align specification decisions to quality goals and indirectly to business goals. Such goals play a role in the following activities: the derivation of software requirements from quality goals, the prioritization of these software requirements, and the definition of decision criteria for architectural design decisions. The results of these three activities influence architectural decisions.
