QFD Online

…moving into the House of Quality

House of Quality (QFD) Example

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.)

House of Quality (QFD) Example
Chocolate Chip Cookie QFD Example

While reviewing the example, you may wish to note the following:

  1. 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.
  2. 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.)
  3. 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.)
  4. HOQ #3 has examples of both of the issues listed in #1 & 2 above.

    nice info..
    it should be usefull for my study

  25. sanjiv said:

    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.

    than you for the templates, they are so useful.

  28. Ravi said:

    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

    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?

  42. Thomas Dwyer said:

    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.

  43. Thomas Dwyer said:

    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.

    Hi
    Can anyone provide me the two example of QFD on similar product, and also tell me which one is the best and why?

  49. Himanshu said:

    Can any one provide me an example of QFD on any Tablet/capsule dosage form.

  50. Aniruddha Gupta said:

    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”
