Here we see the fundamental levels of Enterprise
Transformation based on the fundamental levels of Idealisation/Realisation.
The Direction part of the Enterprise feeds Contextual information into the Transformation part
of the Enterprise which delivers Physical Things
into the Operations part of the Enterprise.
It should be noted that the Transformation part of the
Enterprise may also deliver Physical Things
into the Direction, Support or even Transformation (the whole point of POET)
part of the Enterprise but we just show Operations here as that is the most
The fundamental levels are:
The Enterprise Context consists
of all the things that are not part of the Enterprise (i.e. not directly under
its control) but affect or is affected in some way by it. Things like
Customers, Suppliers, Partners, Regulators, etc.
The Contextual level consists of
the Enterprises Strategy (Mission, Vision, Goals, Objectives, Strategies,
The Conceptual level consists of
Transformational Roadmaps (Business and Technical), Conceptual Structural
Models (Current, Target and Intermediate), and definitions of a series of
programs projects and initiatives that effect the transformation.
The Logical level consists
largely of Logical structural designs.
The Physical level consists
largely of Physical structural designs.
The Operational level consists
largely of the CMDB - Configuration Management Database.
While these levels are often portrayed as separate it should
be noted that the information at each level is not insular. The information at
each level is fundamentally related to the information in the other levels and
it is these relationships which are of paramount importance as they provide the
glue that makes the whole coherent.
Most relationships occur with the information that exists
above and below each level and diminish for levels further away.
This also illustrates that while people may be working with
information primarily at one particular level, they need access to information
at other levels to understand context (from above) and to understand
implications (from below).
In terms of naming these levels there are two fundamentals:
The Enterprise Architecture Model (EA)
consists of Contextual and Conceptual information set in the Context of
Enterprise Context information and Logical information.
The Enterprise Engineering Model (EE)
consists of the Logical, Physical and Operational information set in the
Context of the Conceptual information and the Physical World.
