I like this analogy. Although your example focused on software-centric coordination, I think it's important to also extend it to non-software systems.

An apropos and famous example is the Ariane 5 rocket mishap. The same validated software from the Ariane 4 was used, but the hardware design changed. Specifically, the velocity of the Ariane 5 exceeded that of its predecessor and exceeded the 16-bit variable used.
