Since the business environment is getting increasingly dynamic and complex, the relevant process models in the environment are becoming more complicated. This might easily confuse business experts and lead them to misunderstand the models. Business experts are expecting a simple way to communicate and collaborate with the model developers during business process development and use. Today, enterprise modelling is primarily focusing on goal modeling, resource modeling and process modeling. We propose an additional type of model, which is called business process characterizing model. This model can not only facilitate the efficient communication between business experts and model developers, but also offer an opportunity to handle emergent processes and capture dynamic knowledge and variability.
