The September Topic of ASQ Influential Voice was raised by Paul Borawski (CEO, ASQ) that "Quality should or should not change despite the rapidly changing world". I would like to use the term "Quality Velocity" to explain the trend of faster change on product and service.
On the other hand, some fashion product, like mobile phone, need more new models launching in the shorter period of time but the reliability requirement may be reduced. The old mobile phone (before smart phone) could use for five years as an example. Now the new smart phone's reliability design may be for two years because people would like to change the new fashion smart phone frequently.
