Using a single metric always results in Goodhart's law: when a measure becomes a target, it ceases to be a good measure.

By using "Focus on Impact", people started to focus only short terms.

I believe I have observed a novel form of this law: when a company slogan becomes an article of faith, it ceases to be a good slogan.

The slogan “Move Fast and Break Things” was used until it was serially and irreparably misunderstood.
