engineering fields Overwhelming response to my books on various subjects inspired me to write this book The book is structured to cover the key aspects of the subject Software Engineering The book uses plain lucid language to explain fundamentals of this subject The book provides logical method of explaining various complicated concepts and stepwise methods to explain the important topics Each chapter is well supported with necessary illustrations practical examples and solved problems All the chapters in the book are arranged in a proper sequence that permits each topic to build upon earlier studies All care has been taken to make students comfortable in understanding the basic concepts of the subject Representative questions have been added at the end of each section to help the students in picking important points from that section The book not only covers the entire scope of the subject but explains the philosophy of the subject This makes the understanding of this subject more clear and makes it more interesting The book will be very useful not only to the students but also to the subject teachers The students have to omit nothing and possibly have to cover nothing more I wish to express my profound thanks to all those who helped in making this book a reality Much needed moral support and encouragement is provided on numerous occasions by my whole family I wish to thank the Publisher and the entire team of Technical Publications who have taken immense pain to get this book in time with quality printing Any suggestion for the improvement of the book will be acknowledged and well A A Puntambekar Author iii appreciated Dedicated to God Syllabus Software Engineering CS8494 UNIT I Software Process and Agile Development Introduction to Software Engineering
