It reminds me of Jim Collins' concept (not original to him, I know) of shooting lots of little bullets and seeing which one hits, rather than wasting gunpowder on one big cannonball before you're even sure you're aimed in the right direction.

Except he mostly used that concept to describe how companies decide which individual products or strategies to focus on, while the idea of a pivot is that you shift your entire company to do something else. (Reminds me of another Collins metaphor - it's important to get the right people on the bus first, and then you can decide together where to drive.)
