ROI is the hammer in every leader's toolbox. Applied to executive coaching and employee development, it becomes the wrong tool. Andrews and Laing documented a case where training ran negative for three years before producing a 30% return by year five. A meta-analysis by De Meuse, Dai, and Lee found 70 to 94% of coaching recipients sustained real behavior change. The returns are real. The finance department's ruler just can't measure them. A better question: return on induing.
