An honest inventory of what you have, what works, and what is quietly held together with spreadsheets. The real picture, not the org-chart version.
We map every HR system in production — including the ones nobody officially counts. We catalog the shadow processes (the Excel files HR ops maintains because the standard report does not break down by cost center the way Finance needs it), the integration tape, the manual exports, and the workflow steps that depend on one person knowing what to do.
A defensible baseline of what HR technology actually does — not what the org chart says it does.
