Lineage: why every HR number needs a receipt

When Finance reports a number, the ledger behind it is assumed. When HR reports a number, the pipeline behind it is usually a person's memory of which exports they ran. Lineage closes that gap: every figure carries a traceable path back to the source file, the rules applied and the moment it was computed.
What lineage actually records
- The raw evidence — the exact file or API page that produced the record, hashed so tampering is detectable.
- The transformations — the mapping and validation rules applied, in the version they were applied, not the version that exists today.
- The chain of custody — who or what touched the data at each step, in an append-only audit log.
- The compute stamp — when the metric was last derived, so "this looks stale" becomes a checkable property.
Why it changes the conversation
Without lineage, a disputed number produces a week of archaeology. With lineage, it produces a two-minute walk from the chart to the source row. Disagreement stops being about trust in a colleague's spreadsheet process and becomes a technical question with an answer — which is also what makes external audit, works councils and DPO reviews dramatically cheaper.
How it is built
In Workforce Observatory the path runs through three governed layers — Bronze keeps the immutable evidence, Silver standardizes entities with resolved identity, Gold holds analytics-ready facts — and every published figure references the artifacts underneath it. Nothing enters a dashboard without a receipt. See the governed pipeline.
A four-level people analytics maturity model (L1–L4) — how to score yourself honestly, and why buying above your level is the most expensive mistake.
HRIS says 1,240, payroll says 1,248 — why HR numbers diverge and how a canonical data model, identity resolution and metric lineage create one source of truth.
A people analytics readiness assessment should cover expectations, source inventory, maturity, mapping complexity and current capability — and produce a report that stands alone.
A sustainable people analytics roadmap defines the target state first, then prices two tracks — with a governed platform and without — so every phase defends itself.
Air-gap people analytics explained: no mandatory egress, read-only connectors, verifiable data residency — and what it does not replace inside the perimeter.
