The paper examines one of the corner-stones of the language/action (LAP) approaches: communication loop modelling. This kind of modelling is used in approaches like Action Workflow and DEMO and it includes the modelling of two fundamental roles; customer and performer. The paper extends earlier critical analysis of two-role models. It introduces the principle of multi-responsiveness, meaning that one organisational action can be a response to several different communication acts. The difference between a present triggering initiative and trans-situational background initiatives are described. The paper uses a reference case, the pizza shop case, well-known in the LAP community through earlier use in many papers.
