Certification and Trust
A visible, earned badge
Certified vs uncertified artifacts draw the trust line in BI: certified content passed its gates and shows it; uncertified content is clearly labeled exploratory. Trust lives in visible distinctions.
What you will learn
- Define the certification criteria and its gates
- Distinguish certified from exploratory clearly
- Retire or de-certify content honestly
What is this?
Certification puts a visible, earned badge on content that passed its gates: definition reviewed, control totals reconciled, owner named, tests green, freshness watched. Everything else stays labeled exploratory — not banned, just marked. Trust in BI then becomes mechanical: people anchor decisions on certified artifacts and treat everything else as hypotheses, because the line between the two is drawn in public.
Why do you need it?
- Unmarked content crowds out trusted content — one deck drowns the catalog.
- A visible certification resolves 'is this number safe to decide on?' without a meeting.
- De-certification is as important: trust erodes silently when stale badges linger.
- Every BI team eventually faces the question; the ones with an answer win trust.
Mental model
Food labels: 'organic' vs unlabeled produce
Content certification
The store sells both organic and conventional produce on the same shelf — certified fruit just carries a label proving the claim. Nobody sues the store for having unlabeled apples; you'd sue if the label was a lie. BI is the same: certified badges are what you can rely on; the rest is choice, not fraud.
How it works
- Criteria: a checklist — owner, definition review, control reconciliation, tests, freshness SLA.
- Gates in CI: certification cannot be voted in; it's earned by passing checks.
- Badge surfaced on the artifact — catalog tile, report header — with its review date.
- Exploratory stays available and labeled: 'not certified', with lineage to where it came from.
- Review cadence (quarterly-ish): de-certify stale or changed content with a public notice.
Content earns the badge through gates.
Examples
The certification checklist
REPORT: QBR-revenue-one-pagerOWNER finance-analyticsDEFINITION reviewed 2026-02-01 (formula, grain, filters)CONTROL reconciles to finance system (delta 0.1%)TESTS unit + freshness + schema + drift (all green)SLA daily 06:00 UTC (met 21/21 days)BADGE CERTIFIED - review 2026-02-01, next review 2026-05-01LABEL all other one-pager drafts: "exploratory - unverified"Certification is earned through named gates, badged with a review date, and all else stays visibly exploratory.
In production
- A certified catalog tile filters 'trusted' for exec work; explorers can still test the rest.
- De-certification notice when an owner leaves or a definition changes.
- Certified/de-certified counts reported in the go-to-governance review.
Best practices
- Badge by passing gates, never by committee opinion.
- Certify the definition at the catalog level, so the badge follows the metric.
- De-certify loudly; the notice is part of trust.
- Make wellness visible: review date and freshness on every badge.
Common mistakes
- Certification by vibes — a star because the VP liked it.
- Stale badges: certified forever, content silently changed.
- Exploratory content hidden or deleted — kills the learning half of BI.
- No de-certification path — the catalog rots politely.
Debugging tips
- Trust gap ('is this real?') on every call → badges missing; gate the certification into CI.
- Certified artifact stale → review cadence missed; enforce re-certification dates.
- Duplicated drafts beat the certified one → the catalog line is ambiguous; badge + label loudly.
