For more than thirty-five years, An Introduction to General Systems Thinking has been hailed as an innovative introduction to systems theory, with applications in software development and testing, medicine, engineering, social sciences, architecture, and beyond. Used in university courses and professional seminars all over the world, the text has proven its ability to open minds and sharpen thinking.

Originally published in 1975 and reprinted more than twenty times, the book uses clear writing to explore new approaches to projects, products, organizations, and virtually any kind of system.

Scientists, engineers, organization leaders, managers, doctors, students, and thinkers of all disciplines can use this book to dispel the mental fog that clouds problem-solving. As author Gerald M. Weinberg writes, "I haven't changed my conviction that most people don't think nearly as well as they could had they been taught some principles of thinking."

With more than 50 helpful illustrations and 80 examples from two dozen fields, and an appendix on a mathematical notation used in problem-solving, An Introduction to General Systems Thinking may be your most powerful tool in working with problems, systems, and solutions.

John D. Richards said, ". . . this is one of the classics of systems or science of computing. I recommend it to all; it will cause both scientists and nonscientists to examine their world and their thinking. This book will appear on my reading table at regular intervals, and one day I hope to update to the golden anniversary edition."

He continues, "I've found myself returning to An Introduction to General Systems Thinking again and again in the twenty-plus years since I first stumbled across it. I know no better spark to revive a mind that's stuck in dead-end thinking than to open this book, dive into one of Gerald Weinberg's wonderful open-ended questions, and rediscover how one looks at the world."

"This is a book that is a true classic, not in computing but in the broad area of scholarship. It is partly about the philosophy and mechanisms of science; partly about designing things so they work but mostly it is about how humans view the world and create things that match that view. This book will still be worth reading for a long time to come ..." - Charles Ashbacher
