The Dutch governmental Sociale Verzekeringsbank (SVB) recently completed a project on business modeling. The aim was to develop business models that express the strategic goals of customer event orientation, integrated customer services as well as improved agility. An approach was chosen to combine event definition, dynamic process modeling and business rules. In this paper we present our findings. Main conclusion is that, although we used some best practices and common techniques, we had to invent our own ways to combine event definitions, dynamic processes, object models and business rules.
