A Requirements Pattern

Software Requirement Patterns

Learn proven, real-world techniques for specifying software requirements with this practical reference. It details 30 requirement “patterns” offering realistic examples for situation-specific guidance for building effective software requirements. Each pattern explains what a requirement needs to convey, offers potential questions to ask, points out potential pitfalls, suggests extra requirements, and other advice. This book also provides guidance on how to write other kinds of information that belong in a requirements specification, such as assumptions, a glossary, and document history and references, and how to structure a requirements specification. A disturbing proportion of computer systems are judged to be inadequate; many are not even delivered; more are late or over budget. Studies consistently show one of the single biggest causes is poorly defined requirements: not properly defining what a system is for and what it’s supposed to do. Even a modest contribution to improving requirements offers the prospect of saving businesses part of a large sum of wasted investment. This guide emphasizes this important requirement need—determining what a software system needs to do before spending time on development. Expertly written, this book details solutions that have worked in the past, with guidance for modifying patterns to fit individual needs—giving developers the valuable advice they need for building effective software requirements

A Requirements Pattern

Today's Internet-based software must be developed at a breakneck pace, and it must deliver unprecedented levels of performance, reliability, and availability. Success begins with absolute clarity about requirements. A Requirements Pattern helps developers and project team members gain that clarity, by presenting a proven pattern for building superior Internet-based software. Leading consultant Patricia Ferdinandi begins by demonstrating why requirements are so crucial in today's development environments, and why a modern requirements approach can make it far easier to build successful Internet software. This book introduces software requirements for functional project elements, non-functional elements, and quality levels. It demonstrates how to use requirements to build software that is flexible and can evolve to meet new business needs; how to ask the right questions; and how to manage the requirements process, specifying the most appropriate role for each participant. Ferdinandi even presents a full chapter of e-commerce "anti-patterns" that have proven to fail in real-world development -- and what to do instead. For all software engineers, systems analysts, quality control personnel, project leaders, and other participants in Internet application development projects.
