Another thing is product revisions. Version 1 might be an actual BIFL product. Version 2 might have a small yet significant revision impacting quality. Even process revisions like offloading part of the manufacturing process or a different part supplier can impact the longevity of a product.

There's a famous story that I believe Henry Ford scavenged junk yards for broken Model T's. Every time he found one, he recorded what was broken. After finding enough of them, he figured out the part that was never broken was something like the front axle assembly. So he went to his axle engineers, told them they built it too strong, and find ways to cut costs.
