The creation of a Quality Function Deployment (QFD) typically occurs during the Design phase of the IDOV (Identify, Design, Optimize, Validate) design methodology. QFD is a structured approach used to transform customer needs into engineering characteristics for a product or service, ensuring that the voice of the customer is considered during the design process.

During the Design step, teams are focused on defining and developing the detailed aspects of a solution based on the requirements identified earlier. This is the point where the relationship between customer requirements and technical specifications is established, making it the ideal moment to deploy QFD. It provides a clear framework to align product features with customer expectations, which is crucial for successful design outcomes.

The subsequent phases involve focusing on refining the design and validating the product against the original specifications and customer requirements, but they do not primarily involve the initial application of QFD. Thus, the Design phase is characterized by the integration of tools like QFD to ensure that customer satisfaction is at the forefront of the design process.
