Abstract: This article concerns with the accessibility of Business
process modelling tools (BPMo tools) and business process
modelling languages (BPMo languages). Therefore the reader will be
introduced to business process management and the authors'
motivation behind this inquiry. Afterwards, the paper will reflect
problems when applying inaccessible BPMo tools. To illustrate these
problems the authors distinguish between two different categories of
issues and provide practical examples. Finally the article will present
three approaches to improve the accessibility of BPMo tools and
BPMo languages.
