Test of competency

My friend Matt wrote a startup book. It's really good. One of the points that resonated with me deeply is this one:

"A large turning point is when a founder brings on a fantastic hire who can take vague intentions and wants ("Can you please do  _ / Our goal is to increase _ by X%"), and can consistently do more than you expect."

It's now my new favorite test for both myself and the people I work with.
