Shelving category: Software Engineering/Software Requirements/Requirements EngineeringIntroduction to Requirements EngineeringIan K BrayThe focus of software engineering is moving from writing reliable large-scale software to ensuring that this software meets the needs of the users for whom it was designed. Investigating and describing the (often changing) requirements and their context, together with the determination and documentation of the characteristics of a system that will meet those requirements, is the domain of requirements engineering.This book is intended for undergraduates encountering software requirements engineering for the first time. It is a hard subject for which there is no formulaic approach. It therefore begins with small, relatively simple case studies and builds on these to provide the opportunities to scale up this expertise to large industrial projects. The foundations, so often glossed over, are carefully developed to give the reader an understanding of why particular approaches and techniques are appropriate in different situations.The book is divided into three parts: the first provides a guide to all the important requirements engineering topics, the second gives more detail on useful techniques (for problem definition and modelling), the third contains the complete case studies, extracts from which are used in parts one and two. Requirements engineering is a jargon-filled subject, so a comprehensive glossary is provided as well as definitions within the text. Key featuresCovers all the requirements engineering tasks and documents Clear explanation of the foundations Introduction to all the important techniques Practical guidance on accomplishing the tasks Guidelines for tackling different types of application Examples of complete requirements documents and specifications Numerous pointers for further, advanced studyIan Bray is a part time Senior Lecturer at Bournemouth University, where he has taught requirements engineering to undergraduates and postgraduates since 1990. Previously he held various posts in the software engineering industry including designer, analyst, software quality assurance manager and customer support manager.
