Abstract. General-purpose modeling languages are inadequate to model and visualize business processes precisely. An enterprise has its own vocabulary for modeling processes and its specific tasks may have attached data that define the tasks precisely. We propose using Domain Specific Modeling (DSM) languages to model business processes, such that an enterprise can define its own DSM language(s) capturing its vocabulary and data requirement. We suggest using UML profiles and UML activity diagrams as the semantic base for these DSM languages and present tools that are able to create a DSM language and tool support for a given domain. One tool, called ADSpecializer, can generate a UML profile and its tool support of a given application domain. The other tool, ADModeler, is used to create UML activity diagrams within such a domainspecific UML profile. The two tools enable an enterprise to efficiently define and utilize their own DSM language.
Abstract. There are often three groups of experts involved in the design and implementation of business processes in a service oriented enterprise; business analysts, solution architects and system developers. They collaborate with each other to transform a high-level design created by a business analyst to a final executable workflow, based on a service composition language such as the Business Process Execution Language (BPEL). In this paper, we present a new approach to support and semi-automate this transformation process, thus producing applications of higher quality in shorter time. The idea is to capture existing knowledge in the enterprise, which is required for transforming models from one abstraction level to another, as reusable, parameterized patterns. These patterns are used for tool based model transformations of the business processes. To support our approach, we shall make use of Domain Specific Modeling Languages (DSMLs) designed for each enterprise to capture models of a business process at different levels of abstraction, each suitable for the use of one of the groups of experts. The presented approach bridges the gap between business and IT by providing customizable language-, tool-and transformation support for the different groups of experts within the enterprise and is illustrated by an example.
This work presents experiences with the adopting of a workflow management system in a large financial institution. We describe the gradual evolution of a traditional work process, from manual to computational regulation of coordination. The study shows that computational workflows may increase labor productivity remarkably and in general have significant economic benefits, but also that to make current workflow technologies yield such results requires unorthodox twists and tweaks in the workflow design to allow for worker control and process overview. The paper argues that workflow technology is now at a stage where the contribution of CSCW is obviously needed.
Design and implementation of a business process in an enterprise often requires three groups of experts: business analysts, solution architects and developers. They collaborate to transform a high-level business process to a final executable system based on e.g. BPEL. Since enterprises often utilise their own domain concepts and use technologies in their own specific ways, standard modelling notations and transformations are insufficient. In this paper, we present a methodology to support and semi-automate the transformation of models into an implementation. It advocates the use of a set of domain-specific modelling languages explicitly designed for an enterprise where each language is tailored for the use of one of the three groups of experts. This enables creation of precise and machine-readable models by using domain concepts familiar to the experts. Further, the domain knowledge required for transforming models from one language to another is captured as reusable transformation patterns.
