Query: Requirements get down to reality

I've always found very difficult to apply methodological aspects described in standards, such as CMM, related with requirements.Requirements are especially human-intensive, and this requires very practical approaches to be effective and useful.This book is the result of a wide experience in the field with clear emphasis on the application of requirements.In fact, a couple of aspects are particularly interesting from my viewpoint: users must be involved in the requirements definition and refinement, and requirements have to be complemented with other management elements to make them sense in the global project development arena.I've found this book, clear, useful and well-based.
