Organizations invest billions annually on a success curriculum known as “leadership development,” which ends up leaving so much on the table. Training and development programs almost universally focus factory-like on inputs and outputs — absorb curriculum, check a box; learn a skill, advance a rung; submit to assessment, fix a problem. Likewise, they leave too many people behind with an elite selection process that fast-tracks “hi-pos” and essentially discards the rest. And they leave most people cold with flavor of the month remedies, off sites, immersions, and excursions — which produce little more than a grim legacy of fat binders gathering dust on shelves.
