Source-of-truth coverage
The share of knowledge domains with a single declared authoritative source.
Formula
Source-of-truth coverage
(critical domains with named authoritative source / total critical domains) * 100
Unit
percent
Direction
Higher is better
Cadence
Quarterly; monthly for AI-critical domains.
Numerator
Critical domains with authoritative source
Denominator
Total critical domains reviewed
Worked Example
Information review for executive reporting domains.
Critical domains
26
Domains with named authoritative source
17
Calculation
17 / 26 * 100
Result
65.4%
Interpretation
Leaders and AI systems may be relying on conflicting or unofficial sources.
Recommended action
Assign authoritative sources and owners for the 9 uncovered domains.
Why it matters
This metric helps leaders see whether the information layer is healthy enough to support execution and AI readiness.
What it reveals
Whether leaders and AI systems know which source to trust.
Manual assessment method
List critical knowledge domains and identify whether each has one declared authoritative source.
Lapemo calculation path
Live through knowledge domain source-of-truth coverage and related information health procedures.
Interpretation Bands
Healthy
85-100%
Strong enough for normal operating review.
Watch
70-84%
Usable, but gaps should be assigned owners.
Risk
50-69%
Weak enough to slow execution or create risk.
Critical
<50%
Do not scale the related workflow without intervention.
