Haier's performance management system used several tools to motivate employees and evaluate performance, including colored footprints to indicate performance levels, an "80/20" rule holding some accountable for most work, and a "race track" model with rotating management roles. However, issues included potential feelings of insecurity, loss of expertise from rotations, and loss of employee retention from individual profit/loss tracking. While Haier's system drove initial success, its approaches may not sustain growth or translate well across cultures during expansion.
