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 ofcomplex 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 agiven system;- conduct and manage negotiation and prioritisation processes for the requirementsof a given engineering system;- document the requirements of the system under development, either in naturallanguage or with graphical and formal models. Each chapter includes a set of exercises.

Includes exercises in all the chapters, providing students with the mechanisms to apply/test knowledge, techniques and approaches presented in the book Offers a judicious choice of RE topics, focusing on requirements elicitation, negotiation and documentation Provides many examples on the topics for systems in the software domain and other engineering fields Includes supplementary material: sn.pub/extras

Autorentext

João M. Fernandes and Ricardo J. Machado are Full Professors at the School of Engineering, Universidade do Minho, Portugal. They are active in the software and information systems domain for more than 20 years. Within their research activities, they regularly maintain collaborations with several industrial partners by conducting complex engineering projects.

Prof. Fernandes conducts his research activities in software engineering, with a special interest in software modelling, requirements engineering, and embedded software. He was invited professor/researcher at U. Bristol (1991), Abo Akademi (2002-03), ISCTEM (2003), U. Algarve (2004-06), U. Aarhus (2006--07), and UFSC (2013).

Prof. Machado conducts research activities and has coordinated more than 50 research projects in the field of information systems engineering, with a special interest in modelling approaches

for analysis and design, and in process and project management life-cycles. He is a founding member of the IEEE-IES Technical Committee on Education in Engineering and Industrial Technologies.

In 2009, he received the IEEE MGA Achievement Award.
