PREFACE

Chapter opener image: Zally23/Shutterstock

Essentials of Software Engineering was born from our experiences in teaching introductory material on software engineering. Although there are many books on this topic available in the market, few serve the purpose of introducing only the core material for a one-semester course that meets approximately three hours a week for sixteen weeks. With the proliferation of small web applications, many new information technology personnel have entered the field of software engineering without fully understanding what it entails. This book is intended to serve both new students with limited experience as well as experienced information technology professionals who are contemplating a new career in the software engineering discipline. The complete life cycle of a software system is covered in this book, from inception to release and through support.

The content of this book has also been shaped by our personal experiences and backgroundsone author has more than twenty-five years in building, supporting, and managing large and complex mission-critical software with companies such as IBM, Blue Cross Blue Shield, MARCAM, and RCA; another author has experience involving extensive expertise in constructing smaller software with Agile methods at companies such as Microsoft and Amazon; and the third author is bilingual and has broad software engineering teaching experiences with both U.S. college students and non-U.S. Spanish-speaking students.

Although new ideas and technology will continue to emerge and some of the principles introduced in this book may have to be updated, we believe that the underlying and fundamental concepts we present here will remain.

Preface to the Fifth Edition

The basic concepts and theories of software engineering have stabilized considerably from the early days of thirty to forty years ago. Nevertheless, the technology and tools continue to evolve, expand, and improve every four to five years. In this fifth edition, we cover some of these newly established improvements in technology and tools but reduce some areas, such as process assessment models, that are becoming less relevant today. We will still maintain many of the historically important concepts that formed the foundation to this field, such as the traditional process models. Our goal is to continue to keep the content of this book to a concise amount that can be taught in a sixteen-week semester introductory course. The major modifications to this fifth edition are as follows
