For almost three decades Roger pressman's software engineering: a Practitioner's approach has been the world's leading textbook in software engineering. The new edition represents a major restructuring and update of previous editions, solidifying the book's position as the most comprehensive guide to this important subject. The Chapter structure will return to a more linear presentation of software engineering topics with a direct emphasis on the major activities that are part of a generic software process. Content will focus on widely used software engineering methods and will de-emphasize or completely eliminate discussion of Secondary methods tools and techniques. The intent is to provide a more targeted prescriptive and focused approach while attempting to maintain sepa's reputation as a comprehensive guide to software engineering. The 39 chapters of this edition are organized into five parts – process, modeling, quality Management, managing software projects, and Advanced topics.
