The semantic gap

Semantic gap between

business requirements expressed in a business process modelling language (BPML) . . . . . . and technical implementation expressed in an executable process language

The semantic gap

Manual mapping vs. automatic transformation

error-prone, time-consuming, cost-intensive . . .

Axiom

Horizontal transformation strategy

starting from an abstract business model → manual refinement efforts starting from a business process model augmented with technical details

platform identendence to some extend force business analysts to think in technical concepts

Axiom

Horizontal transformation strategy

starting from an abstract business model → manual refinement efforts starting from a business process model augmented with technical details

platform identendence to some extend force business analysts to think in technical concepts

Axiom

business process models (e. g. BPMN, EPC) must be platform independent platform specific IT implementations (e. g. BPEL) should be derived through a vertical transformation strategy

Stefan Kühne (UniLeipzig) Business to IT Transformations Revisited MDE4BPM 2008 14 / 20

slide-42
SLIDE 42

Axiom’s Consequences and other requirements

Business process model shall not contain any platform specific details, e. g. references to WSDL artefacts Should use refineable proxy elements instead Restrict source models to a subset, which can be unambiguously transformed Full code generation is desirable but not achievable Target models should be comprehensible for human users Iterative development processes through change detection, change visualisation, merge functionalities
