Operation follows MACE. The Phases, Disciplines and
Artefacts are all Enterprise specific for each type of Enterprise - an Oil
Company, a Health Agency, a University, an Aircraft Manufacturer, a Bank, etc. This
is the domain that POEO helps to structure. POEO effectively defines the Conceptual
Operating Model for Enterprise Operation.
Within your Enterprise, Operations is using an Operating
Model - whether it is good or bad, documented or not.
