A framework for the modelling of enterprise operations is presented, aiming at enabling a conception of enterprise operations in three explicitly aligned perspectives: its what, or morphology; its when, or temporal position; its where, or spatial position. It is derived from the precepts of a General Systems Theory and its General Process Theory. The practical and empirical benefit of this framework is indicated by a real-life case, a so-called 'Transatlantic Shopping Process', where the models constructed enable management of complexities emerging from enterprise operations.
