Feature Driven Development

Hi,

I've recently learned about FDD. We are currently working on the dependency view among all the features in a feature model and have developed an user interface for feature model and dependency model.

Now the idea that I wanted to explore is to use the use case to model functional features taken from the feature model. I want to define the use case in detail, I just identify use case associated to each feature. Afterwords this idea may be used to specify component. Like this..........
Feature model -> Functional features ->Use case -> Component

My questions are: 1) Is this something that could work? 2) What should be the intermediate phases? 3) What will happen to the Non-functional features?

Thanks in advance,
Afroza
