Features: Most IT systems fail to meet customer expectations. They either fail to achieve business goals or cannot effectively support users. Why is this? Because the writing of software requirements does not hit the mark. In fact, writing correct requirements specifications does not take much time. This book shows you how: teaching you how to do it faster and more agile. The key points of this book: Through two complete real-world requirements specifications, it explains the traditional and fast approaches to developing specifications, and provides numerous other examples. For different types of projects, such as user-specific needs, COTS, and product development, it analyzes the advantages and disadvantages of traditional and fast specification development methods. It demonstrates how practical examples, including financial analysis, cost/benefit, and other technologies, meet business needs. It explores proven methods for writing complex or challenging requirements. The readers of this book include all personnel related to software. From analysts and developers to the end users, they can learn new methods and benefit from the requirements written by multiple experts, discovering successes and failures from others' experiences. Software suppliers can find inspiration to help customers and write competitive proposals. Programmers and other developers will learn how to express details without excessive technical details and reduce risks in the system development process. Students aspiring to the IT industry can combine theory and practice to learn requirements engineering and lay a solid foundation for future case studies and project development. The failure of most IT systems is related to unclear requirements. This book specifically discusses how to write software requirements faster and more accurately. It introduces the current techniques of requirements engineering in a practical and case-based manner. This book is aimed at all personnel involved in the software supply chain, including analysts, developers, and the end users, who will learn new technologies and gain inspiration from the requirements written by other experts. Software suppliers will learn how to assist customers and write competitive proposals; programmers and other developers will learn how to state requirements without involving too much technical detail, understand how to reduce the risks of system development; IT students will learn the theory and practical experience of requirements engineering and lay a solid foundation for case studies and project development.
