The following House of Quality (QFD) example gives a simple overview of the intended use of a House of Quality matrix and demonstrates how successive HOQs flow into one another, facilitating the Quality Function Deployment process.
This particular QFD example was created for an imaginary Chocolate Chip Cookie Manufacturer (a.k.a. a “Bakery”). The example maps customer requirements to parts/materials to be purchased in order to meet and/or exceed the customer expectations. (The prioritization comes into play when assuming limited availability of funds for making purchases.)
Chocolate Chip Cookie QFD Example
While reviewing the example, you may wish to note the following:
- The QFD ends with HOQ #3. This is due primarily to the fact that all of its parts/materials are purchased rather than manufactured. Had a different product been chosen, a 4th HOQ could have been added that mapped parts/materials attributes to processes and/or initiatives for manufacturing the parts that met those specifications.
- The “Weight” requirement (column #4) in HOQ #1 may not be a valuable requirement. You can tell that this requirement is suspect by the fact that its “Max Relationship Value in Column” is only 1. (Note: the template auto-highlights warning values.)
- The “Weight” requirement (row #4) in HOQ #2 is not being addressed. Similarly, “Tensile Ultimate Strength” (Row #3) and “Size (diameter)” (Row #5) are not being substantially addressed. (Note their “Max Relationship Value in Row” values.)
- HOQ #3 has examples of both of the issues listed in #1 & 2 above.

The example which was provided was really useful for me as a basic learner
February 20th, 2009 at 1:04 am
This example is really helpful in understanding QFD & now I am trying to implement it in public services.

hey!i m from pakistan and i m building a house of quality for bicycle.this example is of great help.thnx alot
June 2nd, 2010 at 12:22 am
hello..!! im from Pakistan.. thanx for providing a great example of HOQ… i have been given an assignment to develop HOQ for a ‘pizza; and ur example has been quite helpful in this regard..
June 9th, 2010 at 7:29 am
thanks for your ex.
June 9th, 2010 at 8:08 am
Thanks a lot for explaining the concept of QFD in just 3 simple and well made charts.
August 27th, 2010 at 11:07 pm
Thankyou sir for a wonderful example. It was really helpful to get a better understanding of how to frame a HOQ by ourselves. Great job. Keep helping forever.
October 5th, 2010 at 10:56 pm
thanks for this ex.which will help me for my ppt.
October 30th, 2010 at 1:10 pm

March 29th, 2011 at 8:49 am
muy bueno
March 29th, 2011 at 11:31 pm
nice info..
it should be usefull for my study
April 3rd, 2011 at 4:17 am
Consider the example of a Ball Point Pen and construct different houses of quality using Quality Function Deployment. Use the standard structure for constructing the houses as per the study materials. (or) Apply the same for a Software Application – Example E-Mail Service. (Note: Answer any of one of these two examples)
Can you please answer the above question.
August 18th, 2011 at 1:06 pm
what a simple and straight forward example! thanks a lot.
October 11th, 2011 at 12:43 am
than you for the templates, they are so useful.
December 19th, 2011 at 3:24 pm
Hi Friends,
Can anyone please guide me to the Weight/Importance column. Does 5 means less importanta and 25 means Highest. If I Rank the features of this column with 1 being most important and 10 being least will it be wrong.
Please guide
Thanks
Ravi

Very nice post. I just stumbled upon your blog and wanted to say that I have truly enjoyed browsing your
blog posts. In any case I’ll be subscribing to your feed and I hope you write again very soon!
June 21st, 2013 at 6:55 pm
Very Nice to shareinformation,sir..! thank’s somuch
August 7th, 2013 at 11:10 pm
I would like to build a QFD for customer demands. Can anybody provide an excel file which would help to build up?
Thanks a lot!
August 13th, 2013 at 9:10 pm
As a basic learner, I could understand the concept very easily with your simple but wonderful example. Appreciate your good work. Keep it up.
October 24th, 2013 at 4:10 pm
It really helped my students. (although they don’t speak English). If wanted, I could help with the translation to Spanish.
Regards

Hello, My name is soheyla. I am studying in Industrial Management in Iran university .I need your help.I cant do my thesis. I read your article but I could not quite understand the issue. I have a problem with filling House of Quality.my thesis is about “Improve the quality of products in food processing with approach using QFD and technique AHP”. Please help me.thanks

This template was a life saver but how do I delete the sheets that I don’t need. I tried to save the Template under a different name but it still comes up as protected. Is there a password that you can give me so that I can remove the extra sheets.

nice, simple example - good way to learn the concepts of a HOQ.
Talking point / question for others:
HOQ# compares the 2 shortening qualities desired.
’softening’ (max relation = 3; relative weight = 5.50 % )
‘crispening’ (max relation = 3; relative weight = 1.60 % )
HOQ#3 compares the 3 shortening types within the relative weights above.
Butter (max relation = 9; total relative weight = 17.2 % )
Vegatable (max relation = 3; total relative weight = 4.80 % )
Margarine (max relation = 9; total relative weight = 6.60 % )
yet Butter is the only shortening that ‘crisps’ and it does not ’soften’ like the other 2 shortening options. Softening has more importance.
Should we use butter or margarine or both?
April 14th, 2014 at 12:24 pm
if you keep your focus narrow, SOFTENING is way more important. HOQ2 says SOFTENING is roughly 4 times more important than CRISPENING.
Then move to HOQ3. BUTTER is at least 2 times as important as VEGETABLE SHORTENING or MARGARINE.
BUT - - BUTTER does not SOFTEN.
April 14th, 2014 at 12:26 pm
Is this a limit of the HOQ methodology?
moderator - please feel free to combine my posts - and fix the word wrap (delete a character or two) on post36 so it doesn’t look so ugly.
cheers.

Perfect example and a great learning tool! Thank you for your time!

Hi
Can anyone provide me the two example of QFD on similar product, and also tell me which one is the best and why?
June 5th, 2015 at 12:57 pm
Can any one provide me an example of QFD on any Tablet/capsule dosage form.
September 15th, 2015 at 11:10 pm
This is a great example for beginners. A few questions to expert/anyone in the team:
1. Is there a method to define the target limits in House1, 2 & 3?
2. What is the significance of the bottom Row “Difficulty” as it does not come up in the final calculation of weightage/Importance?
3. Is the Weightage/Importance value a criteria for defining priorities to meet desired Customer Requirements?
4. What is the final output of “House of Quality”
March 6th, 2016 at 1:06 pm
hey!I am a beginner and i have a few questions of this particular example:
In HOQ #1 where do the numbers on weight/importance come from? 5.0, 10.0, 25.0, 20.0 and 15.0? Is it a out of 30.0 weighing?
What is the purpose of going to the second HOQ and the third HOQ? In order to..?
January 14th, 2017 at 10:34 am
I needed the knowledge in QFD calculation with examples and how can i get the knowledge on
1.Relative importance rating,
2.improvement rating
3.probability distribution
4.probability distribution continuation
5.final importance ratings
6.technical rating
7.technical competitive rating

Thanks for example, helped a lot to understand!
