A Flexible Approach for Abstracting and Personalizing Large Business Process Models

In process-aware information systems (PAISs), usually, dif-ferent user groups have distinguished perspectives on the business processes supported and on related business data. Hence, personalized views and proper abstractions on these business processes are needed. However, existing PAISs do not provide adequate mechanisms for creating and visualiz-ing process views and process model abstractions. Usually, process models are displayed to users in exactly the same way as originally modeled. This paper presents a flexible approach for creating personalized views based on param-eterizable operations. Respective view creation operations can be flexibly composed to either hide non-relevant process information or to abstract it. Depending on the parameter-ization of the selected view creation operations, one obtains process views with more or less relaxed properties, e.g., re-garding the degree of information loss or the soundness of the resulting model abstractions. Altogether, the realized view concept allows for a more flexible abstraction and vi-sualization of large business process models satisfying the needs of different user groups.
