Both SDP and CT can be used to calculate TCO and cost per unit of services - but the models and methodologies are very different in their approach.
It would be useful to understand how these two models and methodologies can be used in conjunction with each other, and how Apptio envisage the products being used together?
The PowerPoint slide above is also somewhat misleading as for CT it shows allocation steps through a service hierarchy - which the standard model and reports do not support. So the SDP "service layers" cannot be easily replicated in the CT model, and would involve a lot of manual effort to build.
Ideally, there should be a way to take the service demand data from SDP (which is essentially a list of consumer/provider pairs and quantities) and load this into CT to replicate the model.
