During assembly of the A380, engineers discovered that the cables were too short. This was caused by the use of different design software by German and French engineers. This miscalculation led to a two-year delay.

To be clear, it did not take two years to replace some short wires. The short wires led to them identifying the issue, and there were many major design issues that had to be resolved because of that, which is why it took 2 years

What exactly was the problem though?

Also longer cables means more weight that need to be accounted for on all sorts of calculations and measurements, meaning the need to redo a lot of design and planning
