Requirements Engineering for Software and Systems
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.

Agile Software Requirements : Lean Requirements Practices for Teams, Programs, and the Enterprise
“We need better approaches to understanding and managing software requirements, and Dean provides them in this book.He draws ideas from three very useful intellectual pools: classical management practices, Agile methods, and lean product development.By combining the strengths of these three approaches, he has produced something that works better than any one in isolation.” –From the Foreword by Don Reinertsen, President of Reinertsen & Associates; author of Managing the Design Factory; and leading expert on rapid product development Effective requirements discovery and analysis is a critical best practice for serious application development.Until now, however, requirements and Agile methods have rarely coexisted peacefully.For many enterprises considering Agile approaches, the absence of effective and scalable Agile requirements processes has been a showstopper for Agile adoption.In Agile Software Requirements, Dean Leffingwell shows exactly how to create effective requirements in Agile environments. Part I presents the “big picture” of Agile requirements in the enterprise, and describes an overall process model for Agile requirements at the project team, program, and portfolio levels Part II describes a simple and lightweight, yet comprehensive model that Agile project teams can use to manage requirements Part III shows how to develop Agile requirements for complex systems that require the cooperation of multiple teams Part IV guides enterprises in developing Agile requirements for ever-larger “systems of systems,” application suites, and product portfolios This book will help you leverage the benefits of Agile without sacrificing the value of effective requirements discovery and analysis.You’ll find proven solutions you can apply right now–whether you’re a software developer or tester, executive, project/program manager, architect, or team leader.

Nonfunctional Requirements in Mobile Application Development
Nonfunctional Requirements in Mobile Application Development is an empirical study that investigates how nonfunctional requirements--as compared with functional requirements--are treated by the software engineers during mobile application development. The book empirically analyzes the contribution of nonfunctional requirements to project parameters such as cost, time, and quality.Such parameters are of prime interest as they determine the survival of organizations in highly dynamic environments.The impact of nonfunctional requirements on project success is analyzed through surveys and case studies, both individually and relative to each other.Sources for data collection include industry, academia, and literature.The book also empirically studies the impact of nonfunctional requirements on the overall business success of both the software development firm and the software procuring firm.Project success is examined to determine if it leads to business success. The book provides rich empirical evidence to place nonfunctional requirements on par with functional requirements to achieve business success in highly competitive markets.This work enhances the body of knowledge through multiple empirical research methods including surveys, case studies, and experimentation to study software engineers' focus on nonfunctional requirements at both project and business levels.The book can guide both computer scientists and business managers in devising theoretical and technical solutions for software release planning to achieve business success.
