Quality Function Deployment (QFD) is a method used to transform customer needs and requirements into detailed engineering specifications and plans to produce products or services that meet those needs. It involves a series of steps and tools to ensure the voice of the customer is heard and addressed throughout the design and production process. Here are the main components of QFD:
- Voice of the Customer (VOC): Collecting and understanding customer needs, expectations, and preferences.
- House of Quality (HOQ): A primary tool in QFD, the House of Quality is a matrix that helps translate customer requirements (WHATs) into engineering characteristics (HOWs). It consists of multiple parts:
- Customer Requirements: Listing what the customers want.
- Technical Requirements: Identifying how to meet those needs.
- Relationship Matrix: Showing the correlation between customer and technical requirements.
- Competitive Benchmarking: Comparing how competitors meet these requirements.
- Technical Priorities: Setting priorities for the engineering characteristics.
- Deployment Process: QFD is not a one-time activity but a process that continues through various stages of product development, including design, production, and after-sales service.
