Quality Function Implementation (QFD) is a product development method that connects customer needs with the design, engineering, development, and manufacturing functions of a product. It was developed in Japan in 1966 and has become popular worldwide. QFD provides quality control for the development process and helps companies develop better products in line with consumer wishes. It can be used for tangible and intangible products, including services, software products, government initiatives, environmental programs, and health plans.
Quality Function Implementation, also known as QFD, is a product development method in which consumers provide information and input to engineers and manufacturers regarding the design and manufacturing process of a particular product from its conception to its manufacture the final. Basically, it connects customer needs with the design, engineering, development and manufacturing functions of a product. The theory is that if customers have a say in every step of product manufacturing, the final product will meet customer needs and generate more revenue. Additionally, implementing quality features can make the manufacturing process more efficient as many problems can be resolved before final production.
Japanese researchers Yoju Akao and Dr. Shingeru Mizuno conceived and developed the implementation of quality functions in 1966. In 1979, a quality control research group specializing in the method of implementing quality functions was formed in Japan . Since that time, it has become increasingly popular in many areas of the world.
One of the theories behind the implementation of quality functions is that it provides quality control for the development process. For the method to work, designers and engineers must understand what the customer wants and what is considered of value from the customer’s point of view. For example, what an engineer wants in a product and what an engineer believes provides value to a product may be different from what a general consumer wants and values.
Many companies view the implementation of quality features as an important planning tool. When used correctly, it can identify key areas where engineers and manufacturers should focus their technical expertise. By directing the attention of those involved in the process, the development method is believed to help the company develop a better product in line with consumer wishes.
Sometimes a company using quality feature delivery will listen to the voice needs of customers. Other times it will listen to unwritten requirements. An analysis of the consumer’s previous purchases or an identifiable gap in the market can also be used to determine the consumer’s needs and requirements.
The distribution of quality functions can be used for tangible items as well as for intangible products. Intangible products using the method include services, software products, government initiatives, environmental programs, and health plans. When used for services, it identifies competitive strategies. It can also document competitive tactics. The goal is to set a new standard for services and other intangible products, focused on consumer satisfaction.
