Applying Quality Function Deployment in Hospitals

What Is Quality Function Deployment?

Quality Function Deployment (QFD) is a structured methodology for translating customer requirements into specific quality characteristics and process parameters. Originally developed in Japanese manufacturing, QFD has been adapted for healthcare to ensure that services are designed around patient needs rather than provider assumptions. CPHQ candidates should understand QFD as a design quality tool that connects the voice of the customer to operational specifications.

The House of Quality

The primary tool of QFD is the House of Quality matrix, which systematically links customer requirements (what patients want) to technical requirements (how the organization delivers). The matrix includes:

• Customer requirements (WHATs): What patients and families identify as important. These are gathered through surveys, focus groups, complaints analysis, and patient advisory councils.
• Technical requirements (HOWs): Specific organizational processes, standards, and specifications that address the customer requirements.
• Relationship matrix: Shows the strength of the relationship between each customer requirement and each technical requirement (strong, moderate, weak, or none).
• Competitive benchmarking: Compares the organization's performance against competitors for each customer requirement.

Healthcare Applications

QFD is particularly valuable when designing new services (such as a new ambulatory surgery center), redesigning care processes (such as the discharge process), or developing new programs (such as a patient portal). By starting with patient priorities, QFD ensures that design decisions serve patient needs rather than organizational convenience.

Implementation Steps

Begin by identifying and prioritizing customer requirements through systematic voice-of-the-customer research. Then identify the technical requirements that correspond to each customer need. Complete the relationship matrix to understand which technical requirements have the greatest impact on customer satisfaction. Finally, set targets for each technical requirement and develop action plans.

Benefits and Limitations

QFD promotes cross-functional collaboration, ensures patient-centered design, and creates documentation that links design decisions to patient needs. Limitations include the time-intensive nature of the process and the challenge of capturing the voice of all relevant customer groups. Despite these limitations, QFD remains a valuable tool for complex design challenges in healthcare.
