Why annual performance reviews destroy your top 20% — the data Adobe, GE and Microsoft already acted on.

When Adobe killed annual reviews in 2012, the framing was 'we wanted to be more agile.' The actual reason, buried in the internal data they published years later, was less inspiring and more honest: their top performers were quitting at almost twice the rate of average performers in the 90 days after the annual review cycle. GE saw the same pattern. So did Microsoft. The annual review wasn't surfacing talent — it was hemorrhaging it.

Why top performers leave fastest

• Top performers already know they're top performers. The review tells them something they knew 11 months ago.
• Forced distribution curves push them into the same bucket as the merely competent — and they notice.
• The biggest 'reward' is usually a 4–6% raise, which is a rounding error against their market value.
• The review surfaces the gap between their self-assessment and the company's calibration — and it's almost always smaller than they hoped.
