Comparing Declarative Process Modelling Languages from the Organisational Perspective

摘要

The spectrum of business processes can be divided into two types: well-structured routine processes and agile processes with control flow that evolves at run time. In a similar way, two different representational paradigms can be distinguished: procedural models and declarative models which define rules that a process has to satisfy. Agile processes can often be captured more easily using a declarative approach. While in procedural languages the organisational perspective can be modelled adequatly, in declarative languages, however, an adequate representation of organisational patterns is often still not possible. Agile processes, however, need to explicitly integrate organisational coherencies due to the importance of human decision-making. This paper presents a review of declarative modeling languages, outlines missing aspects and suggests research roadmaps for the future.
