1. A computer-implemented method for managing a transition between business process models, comprising: in parallel with a first business process model, instantiating, using at least one hardware processor, a second business process model; instantiating a temporary exit process step of a set of temporary exit process steps associated with the first business process model and a temporary entry process step of a set of temporary entry process steps associated with the second business process model; wherein the temporary exit process step is interoperably coupled to the first business process model, the temporary exit process step is interoperably coupled to the temporary entry process step, and the temporary entry process step is interoperably coupled to the second business process model; coupling an exit transition rule of a set of exit transition rules associated with the first business process model to the first business process model; and activating the exit transition rule after activating the second business process model; wherein the exit transition rule determines whether to execute the temporary exit process step.
