1. R. I. T Mechanical Engineering House of Quality Design Project Management Rochester Institute of Technology Mechanical Engineering Department Rochester, NY USA

2. R. I. T Mechanical Engineering Session Objectives Introduction: House of Quality Motivation: traceability Examples Second Hour: individual work/discuss functions, metrics, and mapping with guide

3. R. I. T Mechanical Engineering Remember: This is only a tool! The House of Quality itself is a pretty basic concept Value is in the discussions that arise when applying this tool to your project

4. R. I. T Mechanical Engineering House of Quality Provides a means to relate: Customer needs to engineering metrics Engineering metrics to engineering metrics Provides a means to capture competitive benchmark: Ability to meet customer needs Performance against specs Can include multiple layers

10. R. I. T Mechanical Engineering Why are these important?

11. R. I. T Mechanical Engineering Why are these important? Can help us identify… Unmet needs Overconstrained or over-spec-ed problem Areas where design trade-offs will be necessary Strengths and weaknesses of current products Opportunities to improve on current products Priority areas – what should drive the design?

12. R. I. T Mechanical Engineering Process Check Are there any empty columns or rows? Empty row Customer need not being addressed Empty column Superfluous EM Missing customer need Column with too many relationships EM probably defined too broadly Iterate between VOCs, EMs & Relationships until consensus built Clausing, D., Total Quality Development,: A Step-By-Step Guide to World Class Concurrent Engineering, ASME Press, NY 1994, pp. 135

13. R. I. T Mechanical Engineering Relationship Evaluation: Tips for Success Maintain a high hurdle for significance Less than 50% of the cells should be populated Sanity Check Does the relationship make sense? Is it supported by field data? Don’t skip the discussion Keep it manageable: matrix < 30 x 30 cells Rank order customer needs, address highest priority first Take a poll on each cell Consensus? Move on! Clausing, D., Total Quality Development,: A Step-By-Step Guide to World Class Concurrent Engineering, ASME Press, NY 1994, pp. 133 - 134

15. R. I. T Mechanical Engineering Another way to track specs Spec table List Customer Needs addressed by each Benefits: Ready-made table to demonstrate performance vs. spec Easy to format Drawbacks: Not as comprehensive, less opportunity for discussion Not as visual
