As requirements engineering continues to be recognized as the key to on-time and on-budget delivery of software and systems projects, many engineering programs have made requirements engineering mandatory in their curriculum. In addition, the wealth of new software tools that have recently emerged is empowering practicing engineers to improve their requirements engineering habits. However, these tools are not easy to use without appropriate training.Filling this need, Requirements Engineering for Software and Systems, Second Edition has been vastly updated and expanded to include about 30 percent new material. In addition to new exercises and updated references in every chapter, this edition updates all chapters with the latest applied research and industry practices. It also presents new material derived from the experiences of professors who have used the text in their classrooms. Improvements to this edition include: An expanded introductory chapter with extensive discussions on requirements analysis, agreement, and consolidationAn expanded chapter on requirements engineering for Agile methodologies An expanded chapter on formal methods with new examples An expanded section on requirements traceabilityAn updated and expanded section on requirements engineering toolsNew exercises including ones suitable for research projectsFollowing in the footsteps of its bestselling predecessor, the text illustrates key ideas associated with requirements engineering using extensive case studies and three common example systems: an airline baggage handling system, a point-of-sale system for a large pet store chain, and a system for a smart home. This edition also includes an example of a wet well pumping system for a wastewater treatment station. With a focus on software-intensive systems, but highly applicable to non-software systems, this text provides a probing and comprehensive review of recent developments in requirements engineering in high integrity systems. From the Author: Hear a free podcast based on my requirements engineering book at:spamcast.net About the Author: Phillip A. Laplante, PhD, is professor of software engineering and a member of the graduate faculty at The Pennsylvania State University (Penn State). His research, teaching, and consulting focuses on software quality, particularly with respect to requirements, testing, and project management. Before joining Penn State he was a professor and senior academic administrator at several colleges and universities.Dr. Laplante has consulted to Fortune 500 companies, small businesses, the US DOD, and NASA. He has also served on the technology advisory boards for several companies. Prior to his academic career, Dr. Laplante spent nearly a decade as a software engineer and project manager working on avionics (including the Space Shuttle), CAD, and software test systems. He was also director of business development for a software consulting firm. He has authored or edited 29 books and more than 200 papers, articles, reviews, and editorials.Dr. Laplante received his BS, MEng, and PhD in computer science, electrical engineering, and computer science, respectively, from Stevens Institute of Technology and an MBA from the University of Colorado at Colorado Springs. He is licensed in Pennsylvania as a professional engineer and is a Certified Software Development Professional. He is a fellow of the IEEE and SPIE and a member of numerous professional societies, program committees, and boards. About this title may belong to another edition of this title. Solid requirements engineering has increasingly been recognized as the key to improved, on-time, and on-budget delivery of software and systems projects. New software tools are emerging that are empowering practicing engineers to improve their requirements engineering habits. However, these tools are not usually easy to use without significant training. Requirements Engineering for Software and Systems, Fourth Edition is intended to provide a comprehensive treatment of the theoretical and practical aspects of discovering, analyzing, modeling, validating, testing, and writing requirements for systems of all kinds, with an intentional focus on software-intensive systems. It brings into play a variety of formal methods, social models, and modern requirements writing techniques to be useful to practicing engineers. The book is intended for professional software engineers, systems engineers, and senior and graduate students of software or systems engineering.Since the first edition, there have been made many changes and improvements to this textbook. Feedback from instructors, students, and corporate users was used to correct, expand, and improve the materials. The fourth edition features two newly added chapters: On Non-Functional Requirements and Requirements Engineering: Road Map to the Future. The latter provides a discussion on the relationship between requirements engineering and such emerging and disruptive technologies as Internet of Things, Cloud Computing, Blockchain, Artificial Intelligence, and Affective Computing.All chapters of the book were significantly expanded with new materials that keep the book relevant to current industrial practices. Readers will find expanded discussions on new elicitation techniques, agile approaches (e.g., Kanpan, SAFe, and DEVOps), requirements tools, requirements representation, risk management approaches, and functional size measurement methods. The fourth edition also has significant additions of vignettes, exercises, and references. Another new feature is scannable QR codes linked to sites containing updates, tools, videos, and discussion forums to keep readers current with the dynamic field of requirements engineering. 1.
