Περίληψη

Purpose– The purpose of this paper is to evaluate and improve two popular business process modelling languages (BPMLs) the Integration definition for function modelling (IDEF0) and event‐driven process chain (eEPC).Design/methodology/approach– The paper aims to select, compare and evaluate against a proposed criteria framework two popular BPMLs. In order to meet end‐user requirements, it suggests concrete improvements for either language. Evaluation findings and improvement attempts are documented over a case study within the context of a large European aerospace industry. The languages are applied through the use of appropriate software such as BPWin and Arena Simulation Software for IDEF0 and Architecture of Integrated Information Systems (ARIS) Toolset for eEPC.Findings– Improved languages seem to overcome several deficiencies and increase their modelling performance. Improvements in IDEF0 include: classification of component information and insertion of logical operators. In this approach the language describes not only the information flow within the process, but also the time sequences via component discrimination. Improvements in eEPC include event chain diagram in ARIS house of business engineering methodology, which represents the interrelations between functions of different diagrams and the linkages among components and resources to include resources planning.Practical implications– Results showed that language deficiencies were clarified. Thus, the improvements made, constitute better modelling performance and the development of more reliable models.Originality/value– The paper outlines a systematic evaluation framework with concrete criteria. Furthermore, the improvements made, are a further step towards increased modelling performance, lean and comprehend diagrams.
