Quality Function Deployment (QFD) is a method used in product development to make sure that what customers want is incorporated into the final product. A team works together to create matrices that connect customer needs with product features. By measuring how well these features meet customer needs, the team can prioritize design specifications. This process helps the team focus on the most important tasks and improves communication among team members. Ultimately, using QFD results in a product that is well-designed from the start, reducing the need for changes later on and saving time and money in the development process.
