This open access book establishes feedback as a central organising principle for design and development, offering a new perspective on how individuals and organisations can navigate uncertainty while creating innovative solutions. Designers seek feedback from stakeholders, teams rely on feedback to coordinate their work, managers use feedback to guide projects, and digital technologies increasingly generate feedback across product lifecycles. Yet despite its importance, feedback is often treated as a supporting mechanism rather than a driving principle. This book argues that deliberately attending to feedback can help to create better designs and improve development performance.   The discussion spans design practice, design management, systems engineering, organisational capability and lifecycle digitalisation. It addresses design and development across disciplines using a system-theoretic lens. Questions addressed include: How can designers and organisations use feedback to respond to uncertainty and change? Why do feedback systems often fail to deliver their intended benefits? How does digitalisation enhance and accelerate design and development feedback and what new challenges does this bring?   This book addresses these questions with original contributions, including the Triple Support Model, Feedback Frictions construct and Feedback System Canvas, which together help to explain why feedback succeeds in some situations yet fails to deliver the anticipated benefits in others. Overall, this book provides a coherent framework for diagnosing feedback-related challenges and making the most of design and development feedback.

David C. Wynn has been researching the design and development process since 2002. After completing his undergraduate degree at the University of Oxford and PhD in Engineering at the University of Cambridge, he worked as a researcher at Cambridge Engineering Design Centre and was elected a Fellow of Homerton College. David then joined Bombardier Aerospace in Montreal, Canada where he worked in the Product Development Engineering group, also holding adjunct appointments at the Department of Mechanical Engineering at McGill University and the Faculty of Sustainable Design Engineering at the University of Prince Edward Island. After some time in industry, he returned to full-time academia at the Department of Mechanical and Mechatronics Engineering at the University of Auckland, New Zealand. David then moved to the Kingdom of Saudi Arabia where he is an Associate Professor at King Fahd University of Petroleum and Minerals.
