Quality Function Deployment (QFD) and House of Quality

Quality Function Deployment A methodology defining the customer's desires in the customers own voice, prioritizing these desires, ■ translating them into engineering requirements,and ■ establishing engineering targets for meeting those requirements. QFD produces a technical design specification that can be used to determine best design choices

Quality Function Deployment A methodology „ defining the customer’s desires in the customers own voice, „ prioritizing these desires, „ translating them into engineering requirements, and „ establishing engineering targets for meeting those requirements. QFD produces a technical design specification that can be used to determine best design choices

Why Use Quality Function Deployment？ In a large project with large teams from several disciplines (engineering, marketing,manufacturing,field service,etc.product definition and conception may vary from interest group to interest group. QFD makes sure everyone is viewing the product in the same way

Design without Quality Function Deployment How the customer explained it How the Project Leader How the Analyst designed it How the Programmer wrote it How the Business Consultant understood it described it How the project was What operations installed How the customer was billed How it was supported What the customer really documented needed

Design without Quality Function Deployment

The Quality Function Deployment Method 1.Identify the Customer(s) 2.Determine Customer Requirements/Constraints 3.Prioritize each requirement 4.Competitive Benchmarking 5.Translate Customer Requirements into Measurable Engineering specifications 6. Set Target values for each Engineering Specification 7.Critique design options based on the above to arrive at the best design choice

Experiment with the QFD Process through an example: Designing a Refrigerator Complaints about the old refrigerator include: ■ the refrigerator is unreliable and noisy, ■ the shelves can't hold large containers and ■ cannot be rearranged,and ■ the refrigerator is difficult to clean. Marketing has expressed an interest in the new refrigerator having a water and ice dispenser. Field service has indicated they have experienced failures ■ when refrigerators fall off the delivery truck and ■ have complaints that they are difficult to install

Step 1:Identifying the Customer(s) Who wants the product? Who will build the product and how? Who will sell the product? Who will use the product?

Step 1: Identifying the Customer(s) † Who wants the product? † Who will build the product and how? † Who will sell the product? † Who will use the product?
