This textbook explains software engineering through the use of a case study on the software development lifecycle. The case study covers the development of a DigitalHome (DH) System. A set of scenarios that provide a realistic framework for use of the DH System material are included along with exercises that provide students with an opportunity to engage in the software development practice within a team environment. Each chapter includes mini tutorials that introduce various software engineering topics discussed. Teacher notes and other web resources are available upon qualified course adoption.
