Preventing, finding and fixing defects is necessary to deliver a (reasonably) defect free product. There is an optimum cost (when cost of quality is at its minimum) for (reasonably) defect free products and services, and it depends on the right combination of prevention, detection and correction.
Reasonable for the specific customer needs, that is.
Customers accept these premises on any engineering project except for systems and software ... I guess we are not good at explaining why it is good to test, why it is in the best interest of our customer to test, why validation is necessary even if we have verification in place.
Finding and fixing defects at a cost that is smaller than preventing them is good business, adds value and must be done.
Using our customers resources to find and fix defects that could have been prevented (at a reasonable cost) is wrong, does not add value and must be eliminated.

- Fungus is a name that started as a joke between my son (Magus) and I. I keep it because it helps me remember to be humble and to take myself lightly. Fungi are small and rather simple life forms, but they are very efficient and unstoppable change agents. Fungus
