Ever wonder how fast lightning travels? Did you ever care? The USA Department of Energy gives the speed of lightning as 93,000 miles per second, which maybe a 'rough guide' figure based on the 'half the speed of light' principle!
In business, we are all familiar with the term Efficiency Optimization. This is a non-stop effort aimed at continually improving performance of a given process, function or procedure. The general goal is to have things moving "lightning quick" thereby saving time, money or whatever other metric you are focused upon.
