In a state-based modelling method - Event-B, the next event to be executed is selected non-deterministically among all the currently enabled events. The information about event ordering has to be embedded into guards and before-after predicates of events. This results in entanglement of control flow and functional specification plus the addition of extra variables resulting increased complexity and reduced readability of a model. In this paper we consider Event-B and discuss how to complement the Event-B development process with a workflow view. Proposed approach combines the elements of a workflow language and state-based modelling. Key words: formal modelling, Event-B, workflow.
