This document provides an overview of the Quality Function Deployment (QFD) process and uses an example of designing an improved automobile bumper to illustrate how to apply QFD. The key steps in QFD include: 1) identifying customers, 2) determining customer requirements, 3) prioritizing requirements, 4) benchmarking competitors, 5) defining engineering specifications, and 6) setting target values for specifications. An example bumper redesign goes through each step, constructing a House of Quality matrix to organize the information. The document concludes by noting that a QFD/House of Quality assignment will be due the following Tuesday.

- 1. The Quality Function Deployment Process – House of Quality by Doug Sutton * Turning the customer’s desires into engineering specifications!
- 2. QFD?–Where Are We Headed? • Turn Design Qualities into Design Specs. • Prioritize Design Features • Assess the Competition • Produce a House of Quality – (Which is Due Next Tuesday)
- 3. How The QFD Fits Into Your Final Proposal Proposal Sections: Letter of Intent ----------------->> Transmittal Title Page Executive Summary Table of Contents List of Figures Letter of Intent ------------------>> Introduction QFD/House of Quality ------>> Design Objectives Product, System, or Process Division of Responsibility Project Schedule Budget Resume -------------------------->> Qualifications Bibliography QFD/House of Quality ------>> Appendices Glossary
- 4. The Quality Function Deployment Process 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
- 6. OK, Let’s Walk Through A Simple Example
- 7. QFD Example An Automobile Bumper Customer Request: There is too much damage to bumpers in low-speed collisions. Customer wants a better bumper.
- 8. QFD Example An Automobile Bumper Step 1: Identify Customer(s) – Repair Department – Automobile Owner – Manufacturing Plant – Sales Force
- 9. QFD Example An Automobile Bumper Step 2: Determine Customer Requirements/Constraints – I want something that looks nice (basic) – It must hold my license plate (performance) – I want it strong enough not to dent (excitement) – It must protect my tail-lights and head-lights (performance) – I don’t want to pay too much (basic)
- 10. QFD Example An Automobile Bumper Step 3: Prioritize Customer Requirements
- 11. QFD Example An Automobile Bumper Put prioritized Customer Requirements into a House of Quality Chart
- 12. QFD Example An Automobile Bumper Step 4: Competition Benchmarking – Identify Competitors – Test and Analyze Competitor Products – Reverse Engineer Competitor Products – Rate Competitor Products against customer requirements/constraints
- 13. QFD Example An Automobile Bumper Put competitive benchmarking information into House of Quality Chart
- 14. QFD Example An Automobile Bumper Steps 5 and 6: Translate Customer Requirements into Measurable Engineering Specifications and define target values – Specify how license plate will be held – Specify how to resist dents through material yield strength, young's modulus, etc. – Specify with a dollar amount the term ‘inexpensive’
