The Basis and Core Knowledge of Business Process Management

Imperative Process Modelling

There are two kinds of business process modelling approaches: imperative process modelling and declarative process modelling. Imperative process modelling, which states explicitly the order and alternative ways of execution for a business process model, is categorized into process orchestration modelling and process choreography modelling. Process orchestrations define business process models confined to an organization. In contrast, process choreographies specify cross-organizational workflows that involve collaborations and interactions among multiple business partners. As opposed to imperative process modelling, declarative process modelling states implicitly the order and alternative ways of execution for a workflow by means of constraints.
