This view shows the recursive nature of idealisation/realisation levels in the Structural and Transformational models used.

What this means is that, while there is an overall flow (Contextual, Conceptual, Logical, Physical and Operational) from the top of the transformation stack to the bottom, we also recognise that within each level, information could be Conceptual, Logical or Physical. The Physical sub-level of each level being the required output, but recognising that in order to produce it, work at the Logical and Conceptual sub-levels may be required.

The Contextual sub-level effectively comprises the information from all levels above, and the Operational sub-level effectively comprises the information from all levels below.

At each level (Contextual, Conceptual, Logical, Physical) the information we need to produce at that level is Physical (wrt to that level) but in order to produce it we may need to first build more abstract information (Logical and/or Conceptual).

A good example is where BMM fits, which is at the Contextual level with respect to the whole Transformation domain.

What we need to produce at this level are Objectives and Tactics because this is what is required to feed into the next level. But we can’t just write down our Objectives and Tactics, we need to define more abstract things like Vision and Goals (for Objectives) and Mission and Strategies (for Tactics)

The relationships are much more complicated than that:

¨      An Objective is not part-of a Goal (decomposition), or a type-of Goal (specialisation). An Objective is a transformation-of a Goal (realisation).

¨      A Goal is not part-of a Vision (decomposition), or a type-of Vision (specialisation). A Goal is a transformation-of a Vision (realisation).

¨      A Tactic is not part-of a Strategy (decomposition), or a type-of Strategy (specialisation). A Tactic is a transformation-of a Strategy (realisation).

¨      A Strategy is not part-of a Mission (decomposition), or a type-of Mission (specialisation). A Strategy is a transformation-of a Mission (realisation).

So we can say…

From the pov of the whole Transformation Domain…

From the pov of the Contextual Level…

Enterprise Context

Contextual

Conceptual

Vision, Mission

Goals, Strategies

Physical

Objectives, Tactics

Conceptual

Operational

Physical

 

Operational

 

 

Does your Enterprise represent the information at each of the main levels in terms of Conceptual, Logical and Physical (BMM does)?

If not, would it be beneficial to think in this way?
