Sun Tzu taught a simple formula for creativity. You look at the existing pieces of "best practices." You then take those pieces apart and put them together in a new way. Sun Tzu specifically teaches three views of best practices: how processes look, how they sound, and how they "taste," that is, changing the result they create. As I point out in several of my books, "rearranging" these parts is often a matter of changing their order in time, but those rearrangements are often made possible by advances in other areas usually very remote from the target area.
