Dr. Catherine Chan (President, Hong Kong QFD Association) was the speaker to introduce how QFD deals with VOC. QFD has been used for doing quality planning and product design over 40 years.
Q - Quality which is determined by Customer Expectations (CE)
F - Function which is the "HOW" of the product or service for meeting the CE
D - Deployment which is how suppliers manage the flow of the development efforts so as to make certain that CE drive the development of products and services.
Then Dr. Catherine Chan brief three basic steps of QFD below:
1. Identify the important customers' needs
2. Translate customers' needs into quality elements & identify the important ones
3. Deploy the important quality elements into various aspects to achieve quality
After introduced QFD basic concept, Dr. Catherine Chan said Voice of the Customer was Primary Source of Information for Product/Service Development.
There were 2 Don'ts.
"Don't assume you know customers' needs/requirements."
"Don't Ask Customers What the Product/Service Should Be"
It was because "Not All Customers can tell their Needs/Requirments"
Dr. Catherine Chan stated several ways to collect customer needs such as Observe, Ask, Feel, Listen, Smell, etc. Then she introduced four steps to collect of VOC.
1 - Forecast possible failure that may happen
2 - Work with Representable Customers
3 - Go to the real place to see what to be needed (Gemba 現場)
4 - Propose scenes for the product to be used
She explained how to positively and completely Interpret VOC as follows:
1 - Change negative voice into positive voice
2 - Convert opinions and suggestions into needs
3 - Extract needs from the voice
4 - Add in missing needs from completion
5 - Identify both existing and potential needs
Stop when most of the needs appear to repeat and organize customers' needs into groups
A restaurant case used as an example.
Finally, Dr. Chan used "Innovation" as conclusion to find out more effective and economical way to meeting customer needs.
