Data Quality and Reconciliation: Getting Systems to Agree on a Fixed Calendar
How operators improve data quality and reconciliation across census, billing, payroll and accounting with a system of record and a close calendar.
Download the checklistOperators improve data quality and reconciliation by naming a system of record for each governed field, stating which other systems must agree with it and within what tolerance, and comparing them on a fixed calendar. Every break is assigned to a steward with a due date and fixed at the source record. Reconcile once under governed rules, then stop re-reconciling downstream.
Part of How Operators Govern Data Across Multiple Systems, the six-step operator data governance playbook.
Section 01
Why it matters
Every operator reconciles. The question is whether reconciliation is a governed process or a monthly scramble. In the scramble version, analysts pull reports from each system, line them up in a spreadsheet, adjust the differences and send the result. Next month they do it again, because nothing upstream changed.
Governed reconciliation changes three things. Each field has a named system of record, so the comparison has a reference point. Breaks are routed to the people who can fix the source, so they do not recur. And the calendar is fixed, so owners, lenders and boards know when figures are final.
The result is not a world without discrepancies. Systems will always disagree at the edges. The result is that disagreements are found early, settled by rule and recorded, so the reported figure can be defended.

How to do it
Step 1
Choose the fields that matter most
Start with the figures that appear in owner, lender and board reporting: census, billed days, hours worked, agency hours, care level. A short list governed well is worth more than a long list governed loosely.
Step 2
Name a system of record for each field
Decide which system's value governs. The choice belongs to the domain owner and is recorded in the data dictionary. It may differ by field even within one domain.
Step 3
Set tolerances and cadence
State how closely each comparison system must agree, and how often to check: daily for census, per pay period for labor, monthly for revenue. Tolerances are placeholders until owners approve them: [tolerance].
Step 4
Route breaks to stewards
Each break goes to the field's steward with a due date. The steward fixes the source record, or documents why the difference is valid, and closes the break.
Step 5
Publish a close calendar
Set dates when each period's figures are final. After close, changes go through a documented adjustment with an approver, so final means final.
Step 6
Measure the process
Track open breaks, average days to close and repeat breaks by field. A rising repeat rate signals a definition or workflow problem upstream.

Working template
| Field | Purpose |
|---|---|
| Field and period | What disagreed, and for which period |
| Systems compared | System of record and the system that differed |
| Difference | Size of the break against the approved tolerance |
| Steward and due date | Who will resolve it, and by when |
| Resolution | Source fixed, valid difference documented, or escalated to owner |

Section 04
Common failure modes
- Fixing the report, not the source. Adjusting the spreadsheet makes this month's report right and guarantees the same break next month.
- No system of record. Without a named reference, every reconciliation becomes a negotiation between departments.
- Re-reconciling downstream. When each report team reconciles again, figures diverge between reports. Reconcile once, upstream, and have reports read the governed result.
