This book is about the "how do I do this" of working with clients, users and subject-matter experts, to figure out what they really want and need for their system. This book will put into context the nature of your questions, the environment you need, how long it takes, who should be involved, and the tools you need. You'll also learn how to do it quickly, without missing a thing. You'll really find out what "agile" means - with the results, the specifications, the documentation; but without the chaos.
