Quality Function Deployment of the common quality decision making techniques compares products to the competition
Quality Function Deployment, or QFD, is a model for product development and production popularized in Japan in the 1960s. The model aids in translating customer needs and expectations into technical requirements by listening to the voice of customer.
Although it might sound like a modern testing methodology, Quality Function Deployment (QFD) has a 50-year track record of putting customer needs first throughout the entire product development process. Focusing consistently on customer desires, QFD ensures these are always considered during both the design process and various quality assurance milestones throughout the entire product lifecycle.
The Quality Function Deployment process begins with collecting input from customers (or potential customers), typically through surveys. The sample size for these surveys should be fairly significant because quantifiable data will carry more weight and avoid letting any outlier comments drive product strategy in the wrong direction.
