Exercise: Case Pizzeria

The case Pizzeria is an exercise in understanding and applying the full potential of abstracting from realisation and implementation, and thus focusing on the O-organisation of an enterprise. In the course of its existence, the pizzeria passes through three phases. The transition from the first to the second phase means a change in the essential model. The change appears to have interesting consequences for the allocation of authority. Despite the huge differences between the second and the third phase in terms of implementation, their ontological models do not differ.
