My previous company ran a warehouse and there was a clear bell curve of productivity. Most people were fine, some were excellent, but some were below the level that was realistically achievable. We did careful and considerate analysis and it helped improve productivity.
When done badly however you end up with management using productivity tracking as a lever to increase productivity across the curve. Amazon driver delivery quotas are a great example – people urinating in bottles is clearly a symptom of the quota being too high. Unfortunately software built naively to help bring up the bottom 10% can too easily be used to force up the productivity of the other 90%.
