The success of a business process (BP) depends on whether it meets its business goal as well as non-functional requirements associated with it. BP specifications frequently need to accommodate changing business priorities, varying client preferences, etc. However, since business process goals and preferences are rarely captured explicitly in the dominant BP modeling approaches, adapting business processes proves difficult. We propose a systematic requirements-driven approach for BP design and configuration management that uses requirements goal models to capture alternative process configurations and provides the ability to tailor deployed processes to changing business priorities or customer preferences (i.e., non-functional constraints) by configuring their corresponding goal models at the goal level. A set of design time and runtime tools for configuring business processes implemented using WS-BPEL is provided, allowing to easily change the behaviour of deployed BP instances at a hi...
