- cost of business services in the service catalog (and the forecast for these costs, e.g. is there a path to lower them through a modified EA)
- the unit costs of supporting IT offerings, e.g., CPU, memory, storage, network
- the present value of unused spare capacity and the interest expense of this
- the response time of IT to fulfill service requests, requirements for burst capacity
- the agility of IT to provide new services and eliminate services that are no longer needed
- overhead of managing the existing application and project portfolio
To align the business capability/requirements/priorities with the need to run IT as a business, the IT organization needs to implement IT Financial Management in a way that provides the right metrics and an EA program that takes these metrics into consideration as part of its process. One of the interesting initiatives that is driving the IT Financial Management strategy is Technology Business Management. There is an independent council of IT thought leaders from significant companies that is driving this. You may want to take a look at Technology Business Management Council for more information on this initiative.
