5. Steps to the House of Quality Step 1: Customer Requirements - "Voice of the Customer”: What the customer need or expects. 1.1 Primary customer requirement: Aesthetics Performance 23-09-2012 Dept. of Mechanical & Mfg. 5

6. 1.1.1 Secondary C ustomer R equirements Under A esthetics : Low cost Safe Corrosion resistance 1.1.2 Secondary Customer Requirements Under Performance : Fast Fuel efficiency Reliability 23-09-2012 Dept. of Mechanical & Mfg. 6

7. Step 2 : Technical Descriptors - "Voice of the Engineer”: How to design a product that will meet the customer requirements . Weight Engine power Cost of production Life expectancy 23-09-2012 Dept. of Mechanical & Mfg. 7

8. Step 3: Relationship Matrix: relationship between the technical descriptors and the customers need. Symbols: 23-09-2012 Dept. of Mechanical & Mfg. 8

9. Strong =9 Good =3 weak =1 Step 4 : Correlation Matrix: Relationship between the technical descriptors impact each other. The correlation matrix is probably the least used room in the House of Quality; however, this room is a big help to the design engineers in the next phase of a comprehensive QFD project. 23-09-2012 Dept. of Mechanical & Mfg. 9
