Quality Function Deployment (QFD) is indeed commonly referred to as both "The House of Quality" and "Listening to the voice of the customer."

The term "The House of Quality" is a visual representation used in QFD that helps teams translate customer requirements (the voice of the customer) into specific technical requirements for products or services. This diagram is pivotal in aligning products with customer expectations, creating a structured framework for addressing how to meet those needs effectively.

"Listening to the voice of the customer" is another fundamental aspect of QFD, emphasizing the importance of understanding customer demands and requirements deeply. Successful QFD processes prioritize gathering customer input to ensure that the end product aligns well with what the customer truly desires.

These two concepts are integral to QFD, making the combination of both the correct answer. Each highlights the crucial elements of QFD in ensuring products are developed with a strong focus on customer needs and systematic planning to fulfill those needs through appropriate design and development practices.
