Due to recent market challenges organizational researchers have develo
ped a variety of strategies how organisations can continuously survive
in highly dynamic, sometimes even hostile environments. One of the mo
st important strategies aims to enhance the flexibility of enterprises
through widespread decentralization, while another well-known approac
h advocates customer orientation through systematic business process (
re-) engineering. This paper addresses organizational flexibility and
business process orientation from the perspective of information syste
ms. It starts from a requirements analysis which investigates the chal
lenges of contemporary organizational strategies and then proceeds tow
ards an approach that supports the flexible modeling of business proce
sses by linking decentralized organizational procedures. For this purp
ose a set of process modeling and process interaction operators is def
ined. These operators also allow to automatically create and customize
configurations of computerized business processes. This progress in c
ooperative information processing technology contributes significantly
to the recently emerged concept of the computerized enterprise. The c
oncepts are presented in the context of a banking application, namely
the Credit Advisory Subsystem of our banking application MAMBA.
