An Oldie but Goodie

This book is one of the first books I ever studied on requirements analysis. The Warnier-Orr notation never became mainstream, even during the structured development revolution. With the switch to Object Oriented paradigms, structured analysis notation and techniques have been largely ignored. However, this book has a lot of relevance even today. Orr discusses concepts like entity diagrams, assembly line diagrams, Warnier-Orr diagrams, functional decomposition, and the Of Language. Perhaps the most significant idea is the concept of output-oriented design. Output-oriented design starts with the outputs required of the system and works backward to the design of the database and the inputs. The concept is as valid today as in 1981. The book has a lot of valuable wisdom about system development even 25 years later.

Taken from back cover of book

"Requirements definition is the most critical activity in developing any good system. This book is the first to combine advances in systems theory, tools, and methodology in a readable, workable text." "Ken Orr, president of Ken Orr and Associaates, Inc., is a leader in systems technology "structured revolution" that has swept the computer world in the 70s" "In this book, Orr expands the use of Warnier/Orr diagrams in the requirements process; and introduces yet another major practical tool--the entity diagram."
