Goal-Driven Composition of Business Process Models
2013
Goal-driven requirements engineering is a well-known approach for the systematic elicitation and specification of strategic business goals in early phases of software engineering processes. From these goals concrete operations can be derived that are composed in terms of a business process model. Lacking consistency between goal models and derived business processes especially with respect to the dependencies between goals can result in an implementation that is not in line with the actual business objectives. Hence, constraints indicated from these dependencies need to be considered in the derivation of business process models. In previous work, we introduced the extended goal modeling language Kaos4SOA that provides comprehensive modeling capabilities for temporal and logical dependencies among goals. Further, we presented an approach to validate the consistency between goal models and business process models regarding these dependencies. Extending the previous work, this paper presents a constructive approach for the derivation of consistent business processes from goal models. We introduce an algorithm that calculates logically encapsulated business process fragments from a given goal model and describe how these fragments can be composed to a business process model that fulfills the given temporal constraints.
