Giving something a "7/10" often says very little. It avoids answering the real question of whether it's actually good enough, replacing a clear opinion with a vague score.
When someone asks "how was it?" or "is this good?", a 7/10 score sounds polite, but is really just sitting on the fence:
It protects the reviewer from an uncomfortable conversation, but it leaves the person asking with nothing they can act on.
Note: This isn't a rule against using numbers. Scores like 8/10 or 9/10 can be a great way to recognize good work, especially when paired with specific feedback.
The problem is giving a noncommittal middle score, such as 7/10, without explaining what it means. A clear score backed by actionable feedback is just as useful as a simple pass or fail.
If it's not ready to ship, say so and explain why. If it is ready, say that clearly and specifically.
❌ Figure: Bad example - A vague score gives the team nothing to act on
✅ Figure: Good example - A decisive score plus specific feedback the team can act on
Tip: When requesting feedback, ask reviewers not to use 7/10 and link them to this rule.
