And notably, as a kinda higher-level challenge towards poka-yoke...:
The improper installation apparently required some considerable physical effort, which, somehow did not raise any alarm at GKNPTs Khrunichev's assembly plant in Moscow. (...) By July 13, investigators simulated the improper installation of the DUS angular velocity sensors on the actual hardware. As it turned out, it would be very difficult to do but not impossible. To achieve that personnel would need to use procedures and instruments not certified either by the design documentation or the installation instructions. As a result, the plate holding the sensors sustained damage. Yet, when the hardware recovered from the accident was delivered to GKNPTs Khrunichev, it was discovered that the nature of the damage to the plate had almost exactly matched the simulated version.
(To make it clear, I absolutely love the idea of poka-yoke, and find it great help in software development as well; still, I find the story both hilarious and educative ;) )
