BPMN 2.0 takes dancing lessons – do we need choreographies?

BPMN2.0 1 Comment »

The two BPMN 2.0 proposals are out and already spurred quite some discussion in the BPMN blogging community. One of the changes that seem to remain mysterious about BPMN 2.0 are choreographies. Bruce Silver mentions the “brand new choreography model that nobody understands (or cares about)” in one of his posts. So it’s high time to shed some light on this topic.

First observation: Choreographies are already part of BPMN 1.x.

Really? What is a choreography anyway? I often use the following definition: “a choreography lists all possible interactions between a set of business partners, together with the behavioral constraints between them.” So the focus is on INTERACTIONS.

The Conference on Advanced Information Systems Engineering (CAiSE) is one of the world’s leading academic conferences in the area of information systems and process modeling. This year’s CAiSE took place in Montpellier, France from 16 – 20 June and it featured quite a number of presentations concerning BPMN and “good” process modeling.

Not only could I experience that many BPM researchers share a common interest: following football games. I could also enjoy quite a number of inspiring presentations. In this article I point to some I found particularly interesting.

Do we actually need BPMN?

General No Comments »

The Business Process Modeling Notation (BPMN) has gained major interest from industry and academia. But do we actually need it?

Do we need process modeling?

Process-oriented thinking helps you understand what you actually do in your organization and how the different activities relate. It reveals who depends on whom and what document is created where and why.

Process models help you eliminate waste in your operations and serves as map for pinpointing where you want to change. Process models help you communicate and assign responsibilities for decisions and activities to people.

Process models also help you think about where IT support is useful and where it isn’t.
