A product claim should travel with the conditions that make its evidence relevant. I once supported a loaded-use acoustic claim on the strength of an unloaded demonstration. The later review forced us to hold units and repeat work that should have been planned earlier. I now want the engineering discussion to include the route a trolley must negotiate, the configuration actually supplied and the person who must understand its instructions. A neat test result is useful only when we can explain what it represents.
The unloaded demonstration was convincing enough for me to support a claim about loaded use. It should not have been. In 2017, a later acoustic review found nine of thirty trolley assemblies outside the project's agreed criterion when loaded. We held 120 preproduction units before customer release, delayed introduction ten weeks and incurred ₹48 lakh in testing and redesign. There was no field recall or injury in this fictional account. The mistake was the inference I endorsed between two different conditions, and it changed the way I ask engineering teams to explain their evidence.
