In the era of continuous changes in internal organizationalsettings and external business
environments - such as new regulations and business opportunities - modern enterprises are
subject to extensive research and study. For the understanding design and engineering of
modern enterprises and theircomplexbusiness processes
thedisciplineofenterpriseengineeringrequires sound engineering principles and systematic
approaches based on rigorous th- ries. Along with that a paradigm shift seems to be needed for
addressing these issues adequately. The main paradigm shift is the consideration of an
enterprise and its business processes as a social system. In its social setting an enterprise
and its business processes represent actors with certain authorities and assigned roles who
assume certain responsibilities in order to provide a service to its environment. Second to
that a paradigm shift is to look at an enterprise as an artifact purposefully designed for a
certain mission and goal. The need for this paradigm shift along with the complexity and
agility of modern enterprises gives inspiration for the emerging discipline of enterprise
engineering that requires development of new theories and methodologies. To this end the
prominent methods and tools of modeling and simulation play a signi?cant role. Both
(conceptual) modeling and simulation are widely used for understanding analyzing and
engineering an enterprise (its organization and business processes).
