Based on my understanding of how Core Vitech works with DoDAF, I can see that the services are provided in the columbs in the left. This is an intelligent and functional way to approach DoDAF and the information that can be provided and sought after in DoDAF.
In Rational Rhapsody, erveything is captured in the model. So each model represents the activity. It’s more image based, but Core does not work on any images at all. It’s all about relationships and hierarchy. But that might be because that I’m looking in ER diagram.
This doesn't mean that one is better than other, i just think of it as another approach. Obviously I find Rational Rhapsody's approach more intuitive for the goals of DoDAF, but then Core does it differently. I need to spend more time and do more in analysis.
So Far, this is my candid assessment.
