ABSTRACT
International Standards Organization (ISO). It has been
successfully used, in particular, to ensure semantic inter-
operability between business and IT stakeholders. These
concepts come from mathematics, computing science,
exact philosophy, and systems thinking, and most have
been around for centuries if not for millennia. Reusable
abstract and precise business patterns based on this system
of concepts have been used to create understandable
buzzword-and implementation-invariant specifications
for businesses and information systems. The entry also
presents two small examples of non-toy models.
