This book focuses on various topics related to engineering and management of requirements, in particular elicitation, negotiation, prioritisation, and�documentation (whether with natural languages or with graphical models). The�book provides methods and techniques that help to characterise,�in a systematic manner, the requirements of the intended engineering system.� It was written with the goal of being adopted as the main text for courses on�requirements engineering, or as a strong reference to the topics of requirements�in courses with a broader scope. It can also be used in vocational courses,�for professionals interested in the software and information systems domain. � Readers who have finished this book will be able to: - establish and plan a requirements engineering process within the development of complex engineering systems; - define and identify the types of relevant requirements in engineering projects; - choose and apply the most appropriate techniques to elicit the requirements of a given system; - conduct and manage negotiation and prioritisation processes for the requirements of a given engineering system; - document the requirements of the system under development, either in natural language or with graphical and formal models. � Each chapter includes a set of exercises.
