Maturity Model on Performance Management

I am looking for a model that can be used to determine and communicate the CURRENT and DESIRED STATUS of an organization on Corporate PM.

Typically I would envisage a 5? by 8? Matrix with:
> the horizontal axe consisting out of a number of increasing maturity levels, such as: Recognising, Understanding, Managing, Mastering and Leading.
> the vertical axe consisting out of the dimensions / aspects that one would have to take into consideration, such as:
1) Strategy/Vision,
2) Measuring/Valuation,
3) KPIs/Compensation,
4) Organization/Processes,
5) Culture/Communication,
6) Leadership/Planning,
7) Results/Value Creation,
8) Infrastructure/Tools.

Ideally the cells of the matrix would contain a bulletised description of the qualities an organization would require for a certain maturity level per aspect of Enterprise PM.

This tool could then be used in PM workshops to oversee the complexity of CPM and discuss, graphically plot, and agree on the IST and SOLL status for a particular organization.

Who wants to share work done in this respect? Do you use other tools for this purpose? Why? Can you add builds for the vertical aspects to consider? Please add your Comments!
