The government is proposing a forced ranking system, whereby the bottom 10 per cent do not receive an increment. This is a genuine policy departure.
Forced ranking, famously used by Jack Welch at General Electric, was traditionally reserved for highly individualistic, metrics-driven roles. Even then, the results were often disastrous.
Microsoft abandoned its stack ranking system in 2013, amid criticism that it suppressed innovation and encouraged employees to game the process rather than perform well. Another tech giant, Amazon, also reportedly moved away from the practice.
If private employers are abandoning this instrument, why should Hong Kong’s civil service embrace it?
