Non-functional requirements provide the glue between functional requirements and architectural decisions. Thus, it is important to elicit and specify the non-functional requirements precisely. In practice, however, they are mostly neglected. In this paper, we sketch an approach developed in the context of the EMPRESS project, which allows efficiency requirements to be elicited in conjunction with use cases. This is part of a more general, experience-based approach to elicit and specify non-functional requirements in concert with functional requirements and architecture.
