If a metric becomes a target,
It ceases to be a good measure.
If it ceases to be a good measure,
It will want a glass of milk.
If it wants a glass of milk,
It will want a cookie.
If it wants a cookie,
It will need to become a target.
If it needs to become a target,
It will want to be a measure.
If a metric becomes a target…
How many times do we have to teach you the same lesson, old man?
If a metric becomes a target, It ceases to be a good measure. If it ceases to be a good measure, It will want a glass of milk. If it wants a glass of milk, It will want a cookie. If it wants a cookie, It will need to become a target. If it needs to become a target, It will want to be a measure.
At least once more.
