Measure What Matters
Day 19 of 30 · Done is better - Build What Matters
Opinion ends where data begins.
Learning goal
- Identify metrics that reflect the goal.
- Avoid vanity metrics.
- Use data to decide, not to justify after the fact.
Why it matters
- Vanity metrics mislead.
- Data enables better decisions.
- Opinion ends where data begins.
Key idea
Measure what matters means tracking outcomes that affect the goal, not vanity metrics. Use data to decide; do not use data only to justify after the fact.
Common mistakes
- Measuring what is easy instead of what matters.
- Opinion over data when both are available.
- No baseline or target for the metric.
Today's move
For one goal, name one metric that directly reflects success. Define how you will get the data and how often you will check it.
Self-check
- You can explain the key idea in one sentence.
- You have one concrete move to do today.
