Right, I didn't mention such things as thermal and environmental testing. How is your widget going to work in an Icelandic winter or at the peak of summer in Death Valley? How about dirt, grime, dust, vibration and humidity, rapid cycling, cycles per day, drop, impact? The list is huge and highly dependent on the product being designed. About ten years ago a company owned by a friend of mine shipped a machine worth $800,000 to Japan. The packaging/crate was not designed correctly. The machine suffered irreparable damage during transportation. No, there was no penetration of the crate. It was purely inertial loads on components that were not supported for transportation. They bent. It was probably a combination of forklifts, trucking, port container handling, etc. The machine was a total loss. The insurance company was not happy.
