Blended metrics for PMs: How I’d use them
Our reviewers evaluate writing services independently. Learn how we stay transparent, our methodology, and tell us about anything we missed.
A blended metric combines multiple signals into one number. I'd use them for executive altitude—then always keep the ingredients visible so nobody steers by a smoothie they can't debug.
When I'd blend
- You need one north-star-ish score across uneven inputs
- Stakeholders can't parse five dashboards in a review
- You want balance (e.g., growth and quality)
Rules I'd enforce
| Rule | Why |
|---|---|
| Publish weights | Otherwise it's politics |
| Watch components | Blends hide regressions |
| Revisit weights | Strategy changes |
| Don't bonus solely on the blend | Invites gaming |
Example mindset: a “health” score from retention + support load + latency—useful in a QBR, dangerous if latency tanks and the blend still “looks fine.”
