Solid requirements engineering has become increasingly essential to on-time and on-budget delivery of software and systems projects. As more engineering programs make it a mandatory part of their curricula, students and working engineers require significant training to master the field, especially the complicated emerging ancillary software tools vital to the requirements engineering process.
With a focus on software-intensive systems, Requirements Engineering for Software and Systems provides a probing and comprehensive review of recent developments in intelligent systems, soft computing techniques, and their diverse applications in manufacturing. Topics covered can be applied to the requirements engineering practices for:
To illustrate key ideas associated with requirements engineering, the text presents three common example systems: an airline baggage handling system, a point-of-sale system for one location of a large pet store chain, and a system for a smart home in which one or more PCs control various aspects of the home’s functions. The selected systems encompass a wide range of applications—from embedded to organic, for both industrial and consumer uses.

Appendix: Software Requirements Specification for a Smart Home, Version 2.0
Based on a Penn State course taught by the author, this text provides a review of the theoretical and practical aspects of discovering, analyzing, modeling, validating, testing, and writing requirements for systems of all kinds, particularly software-intensive systems. Incorporating a variety of formal methods, social models, and modern requirements writing techniques useful to practicing engineers, the text is suitable for professional software engineers, systems engineers, and senior undergraduate and graduate students in these fields.
