To improve processes, a formula suggests how many people you will need to train (lots!)

“Generally speaking, the number of people an organization needs to train in process improvement is the square root of the number of personnel.” That rule of thumb, from the Harv. Bus. Rev., April 2010 at 56, means that a law department with 75 people, perhaps 40 lawyers and 35 non-lawyers, would need 8.66 people to get training (the square root of 75) if it were to adequately tackle process streamlining. No legal department has anywhere near that number (or ratio).

Can any reader name a law department, other than the handful that have Six Sigma belts, with even a single person trained to untangle, analyze, and streamline processes?
