Today’s application development requires agile project structures and active involvement of concerned stakeholders. Transforming of representations from requirements specification to executable design models hinders seamless roundtrip engineering and dynamic adaptation. Subject-oriented software processes allow fine-grained modeling and subsequent execution of mutually adjusted stakeholder behaviors representing the business logic of an organization. They enable continuous requirements engineering in the sense of non-disruptive articulation and specification of process knowledge that represents executable software elements. In this contribution we reveal these capabilities of Subjectoriented Business Process Management according to several scenarios of requirements management: (i) development of some business logic starting from scratch, and (ii) extensions and adaptation of behaviors. Each scenario is illustrated by respective business cases.
