We decided to provide you with the entire picture. There are 4 levels to the QFD process with #4 being optional.

A Quality Function Deployment (QFD) is a systematic method to help identify customers' needs for designing a product (or service) in a way that it considers the customers' needs first time.

Topics: Level 1 - The translation fo customer wants and needs into product or service design characteristics utilizing a relationship matrix Level 2: The discovery of which assemblies, systems, sub-systems and components have the most impact on meeting the product or service design requirements and identify key design characteristics Level 3: Examine which of the processes or process steps have any correlation to meeting the component, part or service feature specifications Level 4: Listing all the critical processes or process characteristics in the “Whats” column on the left and then determine the “Hows” for assuring quality parts are produced and list them across the top of the matrix.
