The Quality Function Deployment (QFD) technique helps businesses focus on what customers care about most in a product. It's a tool that guides organizations to prioritize performance, functions, and characteristics that matter to customers. QFD is part of Total Quality Management (TQM) and aims to improve product planning. By following the QFD process, businesses can identify key customer needs, improve product quality, and enhance customer satisfaction. This technique is best used in systems where customer input is crucial. Success with QFD depends on selecting the right team and defining their roles clearly. Proper implementation of QFD can lead to significant benefits for businesses and projects.
