Depending on which Intermediate Model is being defined, its scope, depth and detail is really a function of how far that model is in the future. If it’s the next intermediate model in terms of time, then it will be almost as detailed as the current model. For Intermediate Models that are further in the future, their depth and detail get less and less as they become more aspirational the more into the future they project.

Note that for Roadmapping, we are referring here to the Conceptual layer. The Logical, Physical and Operational layers get populated and filled out as the projects in the roadmap execute.


The information to populate the intermediate model(s) should be provided by an analysis of the Strategy, Current and Target Models. However some Intermediate Model(s) may already exist in the Enterprise in terms of diagrams, drawings and spreadsheets.


Populating the Interim Model(s) is usually done when sufficient clarity is known about one or more objectives.

This usually occurs during Annual Business Planning but can also occur at any time during the year dependent upon the timescales related to the Objectives.


¨      Provision:         Strategic Planning Team.

¨      QA:                 The Board & Senior Management.

¨      Modelling:        Anyone trained in the tool being used.

¨      Update:            Strategic Planning Team.


Populating the Intermediate Model(s) is the result of analysing the Strategy Model, the Current Model (if it exists) and the Target Model (if it exists).

¨      Analyses Strategy, Current & Target Models

¨      Determine the number of Intermediate Models

¨      For each Intermediate Model

¨      Analyse its Objective(s)

¨      Load the information

¨      QA the information


Questions to ponder...

How would you describe your Enterprises long term Target?

What are some of your Enterprises short and mid term business objectives?

What are some of your Enterprises short and mid term IT objectives?

Do people working on projects know what these objectives are?
