Reduce the incidence of duplicate and inconsistent requirements; Communicate requirements that are understandable to both users and developers; Prototype the right system well before the design phase is underway; Document the entire requirements process clearly and efficiently.
Use Cases: Requirements in Context first examines the difficulties of requirements gathering and briefly introduces both use cases and the Unified Modeling Language (UML). Using detailed examples that run through the book, it then elaborates a four-step method for establishing requirements--an iterative process that produces increasingly refined requirements.

They also reveal common mistakes and pitfalls to avoid.
