This presentation deals with business IT alignment from a capabilities perspective - actually actively promotes the use of capabilities based model and iterative development and implementation.
The best part is the attempt to explain and provide a solution to the complexity that comes with a diversified/distributed corporate structure - how does one align business with IT when the "business" has several business units/divisions?
The presentation provides an excellent overview of business IT alignment with different scenarios. As with any presentation, unfortunately, you will have to read between the lines a lot.
Very good read!
