Improving the Quality and Cost-Effectiveness of Process-Oriented, Service-Driven Applications: Techniques for Enriching Business Process Models
Abstract
A key objective of any Service-driven architectural approach is to improve the alignment between business and information technology (IT). Business process management, service composition, and service orchestration, play major roles in achieving this goal. In particular, they allow for the process-aware integration of business actors, business data, and business services. To optimize business-IT alignment and to achieve high business value, the business processes implemented in process-aware information systems (PAISs) must be defined by domain experts, and not by members of the IT department. In current practice, however, the information relevant for process execution is usually not captured at the required level of detail in business process models. In turn, this requires costly interactions between IT departments and domain experts during process implementation. To improve this situation, required execution information should be captured at a sufficient level of detail during business process design (front-loading). As another drawback, existing methods and tools for business process design do not consider available Service-oriented Architecture (SOA) artifacts such as technical service descriptions during process design (look-ahead). Both front-loading and look-ahead are not adequately supported by existing business process modeling tools. In particular, for many process aspects, appropriate techniques for specifying them at a sufficient level of detail during business process design are missing. This chapter presents techniques for enabling front-loading and look-ahead for selected process aspects and investigates how executable process models can be derived from business process models when enriched with additional information.
