Today’s Topic – Simple QFD
• Quality Function Deployment (QFD) is a complex but powerful tool that is used for product development
• Today we will focus on a simplified version that can be used for process design
![Page 6: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/6.jpg)
QFD Simplified for Process
• History and purpose of Quality Function Deployment (QFD)
• Simplified version that can be used for process design
• Some examples
![Page 7: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/7.jpg)
History of QFD
• Developed in the 1960’s by two professors in Japan
• Purpose was to design customer satisfaction into products
• Refined in 1970s
• Caught on in the US in the 1980’s and 90’s for product design
![Page 8: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/8.jpg)
House of Quality
• Quality Function Deployment (QFD) is recognized for the matrix which translates customer requirements (the voice of the customer) into technical requirements • The matrix is often referred to as the “house of quality”.

Why is QFD Good?
It’s a Translation Tool
![Page 10: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/10.jpg)

Customers are Hard to Understand
![Page 12: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/12.jpg)
Great Tool but……
• Very long and tedious method
• Correct application requires rigor and time
• Hard to translate from product to process
![Page 13: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/13.jpg)
Typical Team Reaction
Had this experience?
![Page 14: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/14.jpg)
Adapting Tools to our Needs
• QFD is a great tool for product development or even complex process development
• Most of us spend more time on small pieces of internal processes
![Page 15: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/15.jpg)
Simplified Approach
• What if we could apply the idea in a much simpler way?
• Translate customer requirements without confusing out teams
• Let’s make the tool work for us, not us working for the tool

Needs – Something a Customer would say they wanted – you could hear this coming from a customer’s mouth
Requirements – Something measurable – you can tell how you are doing in comparison – but generic – doesn’t imply a solution
Specifications – Something measurable from a specific design or process– design parameters and process parameters
Needs, Requirements, and Specifications Focus Today

Voice of the Customer is both qualitative and quantitative
• A complete set of customer wants and needs
• Expressed in their own language
• Organized into a hierarchy
• Prioritized by importance and current performance or satisfaction
What are Customer Needs
*
![Page 26: Translating Customer Expectations with Quality Function Deployment (QFD) · PDF file · 2016-05-17Translating Customer Expectations with Quality Function Deployment (QFD) Sheryl Vogt](https://reader031.vdocuments.net/reader031/viewer/2022030415/5aa10f9e7f8b9a62178f0569/html5/thumbnails/26.jpg)
Do you know what data you already have?
Capturing Customer Needs
• Look for existing information – Historical data – Complaints – Standards and Regulation – System specifications
• Conduct Surveys
• Conduct Team Meetings and Focus Groups
• Conduct individual interviews

Relative Importance of Needs – we usually use a scale of 1-5 or 1-10. (You may need to understand which customers matter most before you do this)

What is a Customer Requirement?
• Something that measures whether the customer need is met
• Not a solution, but may point the way to solutions
• Should not be design / implementation specific
• What measures might the customer use to determine whether the need is met?
Sometimes we get many of these in our VOC *

Developing the List Use tools to group like needs together & identify high level requirements • Affinity diagram
• Tree diagram
• Brainstorm (this is the creative part)
Make sure requirements are clearly stated
Try to keep requirements to five words or less

Entering Customer Requirements
Requirements – Something measurable – you can tell how you are doing in comparison – but generic – doesn’t imply a solution

Similar to C&E but Not Quite

Relationship Score
• Scoring is like the C&E Matrix • 1, 3 and 9
• The criteria for each score: • Blank = No relationship • 1 = The customer requirement only remotely
affects the customer need • 3 = The customer requirement has a moderate
effect on the customer need • 9 = The customer requirement has a direct and
strong effect on the customer need

Requirements Rating
Rate the customer requirements by multiplying the customer need rating with the relationship score and summing by customer requirement.

Summary
• QFD (Quality Function Deployment) is a very powerful tool to translate the customer voice into something measureable
• We can use a simplified version in smaller process
design projects • The result is a good translation of customer needs
that teams can do easily and much more quickly
