The goal of the MOKASSIN project is to support business-process and sy
stems integration. Existing applications will be agentified in order t
o enable their interoperability. The behaviour of the entire system co
mprising heterogeneous applications should be guided by business-proce
ss models. Based on several case-studies the main requirements were de
rived. These case studies showed that thinking in terms of processes m
ay be valuable for analysis purposes but not For the specification of
the users-needs, Due to the interesting insights we gained the case-st
udies are outlined in more detail in this paper. From a systems point
of view the end-users can be classified into users of information syst
ems and users of intelligent systems. The following chapters will expl
ain in detail how MOKASSIN supports both of these user-groups with an
agent-based workflow system. (C) 1998 Elsevier Science S.A. All rights
