An Analytical Evaluation of BPMN Using a Semiotic Quality Framework

Evaluation of modelling languages is important both to be able to select the most suitable languages according to the needs, and to improve existing languages. In this paper Business Process Modeling Notation (BPMN) is presented and analytically evaluated according to the Semiotic Quality Framework. BPMN is a functionally oriented language well suited for modeling within the domain of business processes, but probably also general processes not only within the business domain. The evaluation indicates that BPMN is easily learned for simple use, and Business Process Diagrams (BPDs) are relatively easy to understand. Tools may fairly easily map BPDs into the BPEL4WS format, but executable systems then require creation of Web Services representing the Activities in BPDs. An evaluation according to the BWW ontology is useful for finding ontological discrepancies, and the semiotic framework is useful for evaluating quality on a relatively general level. These methods thus complement each other.
