Clear, written one-minute goals eliminate the ambiguity that undermines performance

The authors argue that most performance problems trace back to unclear expectations rather than lack of effort or ability — employees often genuinely don't know what "good" looks like for their role, and managers assume shared understanding that was never actually established explicitly.

Their fix is deliberately simple: agree on no more than a handful of key goals, write each one down in roughly a single paragraph, and ensure both manager and employee can read and review it in about a minute. The brevity is intentional; a goal too long or complex to state simply is unlikely to be clearly understood or remembered day to day.

This isn't a replacement for deeper planning, but a discipline for making sure the fundamental expectations are unambiguous and easily revisited, since vague or overly elaborate goal documents tend to get filed away and forgotten rather than actually guiding daily behavior.

Takeaway: if a goal can't be reviewed in a minute, it probably isn't clear enough to act on.
