When targets and metrics are bad for business
But Otis came to learn that metrics weren’t inherently bad — his bosses had just failed to grasp two important economic principles:

Goodhart’s Law: “When a measure becomes a target, it ceases to be a good measure," and
Campbell’s Law: The more a metric is used, the more likely it is to “corrupt the process it is intended to monitor.”

He realized that when his performance was measured with a specific metric, he optimized everything to hit it, regardless of the consequences that arose. As a visiting professor at the London School of Economics told him, improper targets could:

Encourage “gaming” the system (e.g., bagging free groceries)
Incentivize the wrong aspects of work (e.g., writing trivial code)
Erode morale (e.g., writing clickbait)
Harm customers (e.g., turning away critical surgery patients)

Watts in a Name? Why We’re Using Watt-Hours to Compare Batteries
“...because milliamp-hours don’t take voltage into account, and because voltage affects the amount of power a battery can deliver, mAh ratings are imperfect across similar batteries and just plain bad for comparing different types of batteries....”

WeChat Takes On Alibaba With 'Payments Score' | PYMNTS.com
WeChat is now using a rating system to determine if a user is eligible to receive perks, including deposit-free renting services.
WeChat Payments Score soft-launched last November in eight cities, and the system is being tested out on certain apps, including Tencent-backed bank rental service Xiaodian, which will waive deposits for users if their rating hits a certain benchmark.
While it’s unknown how WeChat calculates the points, reporters performed a test that revealed the system factors in a user’s shopping and contract-fulfilling history.
WeChat’s rival, Alibaba’s Ant Financial, has had a similar assessment system in place since 2015, which measures similar factors. People with higher scores enjoy perks like deposit waivers for hotel stays.
