Description
"If the purpose is to create one of the best books on requirements yet written, the authors have succeeded."
—Capers Jones
It is widely recognized that incorrect requirements account for up to 60 percent of errors in software products, and yet the majority of software development organizations do not have a formal requirements process. Many organizations appear willing to spend huge amounts on fixing and altering poorly specified software, but seem unwilling to invest a much smaller amount to get the requirements right in the first place.
Mastering the Requirements Process, Second Edition, sets out an industry-proven process for gathering and verifying requirements with an eye toward today's agile development environments. In this total update of the bestselling guide, the authors show how to discover precisely what the customer wants and needs while doing the minimum requirements work according to the project's level of agility.
Features include
- The Volere requirements process—completely specified, and revised for compatibility with agile environments
- A specification template that can be used as the basis for your own requirements specifications
- New agility ratings that help you funnel your efforts into only the requirements work needed for your particular development environment and project
- How to make requirements testable using fit criteria
- Iterative requirements gathering leading to faster delivery to the client
- Checklists to help identify stakeholders, users, nonfunctional requirements, and more
- Details on gathering and implementing requirements for iterative releases
- An expanded project sociology section for help with identifying and communicating with stakeholders
- Strategies for exploiting use cases to determine the best product to build
- Methods for reusing requirements and requirements patterns
- Examples showing how the techniques and templates are applied in real-world situations

描述：
「如果目標是創造有史以來最好的需求書籍之一，作者已經成功了。」- Capers Jones
廣為人知，錯誤的需求佔軟體產品錯誤的60％，然而大多數軟體開發組織並沒有正式的需求流程。許多組織似乎願意花費大量資源來修復和修改不明確的軟體，但卻不願意在一開始就投資少許資源來確定需求。
《需求管理的精髓：第二版》提供了一個經過業界驗證的流程，以應對當今敏捷開發環境下的需求收集和驗證。在這本暢銷指南的全面更新中，作者展示了如何精確地發現客戶的需求，並根據項目的敏捷程度進行最少的需求工作。
特點包括：
- Volere需求流程-完全規範化，並經過修訂以適應敏捷環境
- 可用作自己需求規範基礎的規範模板
- 新的敏捷度評級，幫助您將努力集中在特定開發環境和項目所需的需求工作上
- 如何使用適應性標準使需求可測試
- 迭代需求收集，加快交付給客戶的速度
- 檢查清單，幫助識別利益相關者、使用者、非功能性需求等
- 針對迭代版本收集和實施需求的詳細資訊
- 擴展的項目社會學部分，以幫助識別和與利益相關者溝通
- 利用用例確定最佳產品建構策略
- 重複使用需求和需求模式的方法
- 在實際情況中展示技術和模板的示例
