Lineage completeness
The share of governed outputs whose information chain traces to an owned, governed source.
Formula
Lineage completeness
(outputs with traceable upstream source, owner, and timestamp / total outputs sampled) * 100
Unit
percent
Direction
Higher is better
Cadence
Quarterly; before high-stakes AI deployment.
Numerator
Outputs with complete lineage
Denominator
Outputs sampled
Worked Example
Executive dashboard metric lineage review.
Dashboard metrics sampled
40
Metrics with complete lineage
24
Calculation
24 / 40 * 100
Result
60%
Interpretation
Important outputs cannot reliably be traced back to evidence.
Recommended action
Prioritize lineage for metrics used in decisions and AI workflows.
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 decisions and outputs can be traced back to reliable evidence.
Manual assessment method
Select key outputs and trace their upstream information sources, owners, and governance status.
Lapemo calculation path
Supported by lineage queries; percentage assembly can be built from governed outputs and upstream sources.
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.
Required inputs
- Output sample
- Upstream source
- Source owner
- Timestamp
- Transformation path
Data sources
- Data lineage tool
- Dashboard inventory
- Knowledge object records
- Audit logs
Common pitfalls
- Confusing source links with full lineage
- Not checking owner and timestamp
Recommended actions
- Document upstream sources
- Assign owners
- Add timestamps to critical outputs
Measure Before You Scale
Measure the operating model before AI amplifies it.
