The term most closely associated with Quality Function Deployment (QFD) is indeed the House of Quality. The House of Quality is a key tool within QFD that visually represents the relationships between customer requirements and the technical features of a product or service. It organizes and prioritizes the voices of the customer, ensuring that their needs are considered during the design and development process. This alignment helps teams focus on delivering quality outcomes that meet customer expectations.

SIPOC, while useful for understanding processes by identifying Suppliers, Inputs, Processes, Outputs, and Customers, does not specifically relate to the core functions and structure of QFD. A process flow diagram illustrates the steps in a process but does not encapsulate the customer-centric approach of QFD. Focus groups can provide customer feedback, but they are not a structured methodology like the House of Quality that integrates that feedback into product design. Thus, the connection of QFD to the House of Quality is clear and central to its purpose.
