This is simply too good to pass by, especially with the Grand Prix coming this weekend. Task in question: change tyres on a race car. Time in question 1950 and 2013. The result: what took 67 seconds to change just 2 front tyres in 1950, takes less than 4 seconds now.
Somewhat surprisingly, the way the wheel is attached to an axle has not actually changed. In both cases it is just a single center nut. What did change is the tools: it took several seconds just to get the nut off, mind you, with a hammer. Today pneumatic driver does it in a fraction of a second.
Having more mechanics (20 vs 3) also helps. However, also apparent is a much greater focus of operations: everybody has a very specific task. Focus necessitates coordination, and the result speaks for itself.
