Stages towards business orientation for it-organisations

I think there are some more stages than component orientation and service orientation in IT organisations which makes it easier for organisations to make progress on this long road visible:

1.  Purely technical orientad organisations don't manage IT really. They operate technical items as good as they personally can.
2.   Product orientated organisations know the connections between products (e.g. applications) and there specific operation envirements.
3. Component orientated organisations are able to manage less operations envirements than products exist. They manage technical services as a technical serviceprovider.
4.   Customer focused organisations often try to fulfill the customer expactations, but "forget" the technical abilities and costs. Selling is everything...
5. Service orientated organisations are able to close this gap between customer expactions and provider abilities.
6. The most challenging model is in my opinion the business orientation: The IT organization is able to manage services by maximizing the efforts for customers and the business.
