The Wedge Framework

The Wedge Framework is a three dimensional framework into which any and all change initiatives within an enterprise can be mapped and unified.  The three dimensions are scope, business time and the level of impact.


The 3 Dimensions of Change

1. Scope is defined in terms of the

business model components being impacted by the change. e.g. system x, process y, role z.

2. Business Time is the time at which the change will take effect in the operational business (as opposed to the time at which the change is being worked on).

3. Level of Impact shows to what extent the change will impact the business as described at various levels, from vision down to operations.  These levels equate to conceptual, logical, physical and actual.


The higher the level in the change lifecycle, the further out in time the change is likely to be.  This gives the Wedge Framework (the Wedge) its characteristic sloping edge where all the current initiatives are taking place.  As time progresses the change initiatives progress down through the levels, vision turns into architecture, architecture turns into design and so this edge moves forward.  Meanwhile, smaller, lower level changes are being made.  They must be unified if they aren't to interfere with each other.

Each layer in the Wedge contains a description of the business at the appropriate level of abstraction.  For example the top layer, Vision, can be described using the Business Motivation Model.  There are a variety of techniques for describing the models in the various layers.  The important factor is that each layer is complete (i.e. all processes are identified) and consistent and that there are linkages between the layers to enable traceability.

Any change can be described in the three dimensions of the Wedge and thus can be envisaged as occupying a space within the Wedge.  This space is called the 'Change-Space'.  Key to this is the proper definition of a change's scope using common business models.

Using the Wedge and the Change-Space concepts, enterprise wide business change management and co-ordination, or Unified Business Change ManagementTM as we call it,  becomes the instigation, unification and management of these Change-Spaces. Duplication and contention between changes can be identified and removed at source, wasteful current state analysis minimised, and all change efforts can be integrated and aligned towards a common goal, the corporate vision. 

Implementing this framework and the processes that support it will provide management with the necessary ability to drive their businesses as discussed in our Changeability paper (requires Acrobat Reader 5).  

Our services are based on these basic concepts.  Should you wish to discuss this further then please contact us.
