Construction · Lesson 08
Impact without invented metrics
Use quantitative, qualitative, operational, risk, customer, and learning evidence without overstating causation.
What you will learn
- Use quantitative, qualitative, operational, risk, customer, and learning evidence without overstating causation.
Use an evidence ladder
Prefer a verified metric when available. Otherwise name an operational observation, customer report, artifact, decision, avoided risk, or later behavior. Do not manufacture precision to make a story sound senior.
- Where did the evidence come from?
- What measurement window applies?
- What outcome remained unknown?
Separate contribution from causation
State what your action plausibly influenced and what else changed. A truthful caveat often strengthens credibility because it shows measurement judgment.
- What other contributors existed?
- Was the comparison controlled?
- Can you claim direction without claiming exact magnitude?
Reliability without revenue attribution
A candidate fixed a recurring deployment failure but cannot access revenue data.
My fix saved the company millions and improved reliability by 95%.
I removed the race that caused three documented rollbacks and added a pre-deploy concurrency test. The next eight deployments did not reproduce that failure. I do not have evidence linking the change to revenue.
- The evidence is inspectable.
- The window and failure class are bounded.
- The unavailable business metric is not invented.
Rewrite one story outcome using the strongest evidence you actually have.
- 1Name the source and window for every number.
- 2Add one non-numeric evidence type.
- 3Write a causality caveat in plain language.
Open the answer check
The result should remain meaningful if every unsupported percentage or dollar estimate is removed.
