The tyranny of metrics

One criticism of metrics is the obsession with numbers leaves no space for qualitative assessment.

Numbers present a deceptive quality of objectivity. We tend to think of data as representing objective truth, but it does not always deserve the authority we give it.

• Tracking metrics can take away from the actual work.
• When pressured to reach specific numbers, people will game the system.
• Tying metrics to rewards and punishments destroys intrinsic motivation.
