When you spend your days working with numbers, you become familiar with miscalculations. Something is coded as travel expense when it’s really a meal, someone transposed a 5 and an 8, and you’d swear that 7 really looked like a 1. All of these are things we need to get right in our business, the same way engineers need to be exact in their calculations and contractors measure twice and cut once.

Once in a while though, everyone makes a misstep in the process, most times it’s caught, rarely it’s not. This article, inspired by an order of trains by the French that are too wide for most of the platforms in the stations, describes a few of the more humerus ones, proving asking “does this make sense” is usually the right thing to do. It’s from the BBC, so please excuse the British English.
