The fifth edition of Software Engineering A Practitioner's Approach is intended to serve as a guide to a maturing engineering discipline. The fifth edition, like the four editions that preceded it, is intended for both students and practitioners, retaining its appeal as a guide to the industry professional and a comprehensive introduction to the student at the upper level undergraduate or first year graduate level. The format and style of the fifth edition have undergone significant change, making the presentation more reader-friendly and the content more easily accessible. The fifth edition is considerably more than a simple update. The book has been revised to accommodate the dramatic frowth in the field and to emphasize new and important software engineering practices. The 32 chapter of the fifth edition have been organized into five parts. This has been done to compartmentalize topics and assist instructors who may not have the time to complete the entire book in one term. Part One, The Product and the Process, presents an introduction to the software engineering milieu. It is intended to introduce the subject matter, and more important, to present concepts that will be necessary for later chapters. Part Two, Managing Software Projects, presents topics that are revelant to those who plan, manage and control a software development project. Part Three, Conventional Methods for Software Engineering, presents the classical analysis, design, and testing methods that some view as the "conventional" school of software engineering. Part Four, Object-Oriented Software Engineering, presents object-oriented methods across the entire software engineering process, including analysis, design, and testing. Part Five, OAdvanced Software Engineering Topics, presents dedicated chapters that address formal methods, cleanroom software engineering, component-based software engineering, client/server software engineering, Web engineering, reengineering, and CASE.
