How to audit Span of Control, Org Layers, and Payroll Rollups from a roster
Load your current roster or M&A reorganization draft (.xlsx / .csv)
Drop your spreadsheet into the local workbench. OrgLayout recursively traverses every reporting line from L1 CEO down to L5+ individual contributors.
Inspect Direct Span, Total Rollup HC, and Layer Depth per manager
Review the right-hand Traceable Rollup Summary table showing each leader’s Org Layer (L1–L5), Direct Reports (Span), Total Subtree Headcount, Rollup Payroll, and exact Source Excel Rows.
Export the 3-Sheet Traceable Rollup Workbook (.XLSX) & Board Deck
Download the 3-sheet Excel audit workbook (`Dept & Manager Rollup`, `Reconciled Hierarchy`, and `Flagged Roster Exceptions`) alongside synchronized 16:9 PDF and .PPTX slides.
Why manual Excel pivot tables fail at multi-layer org hierarchy rollups
| Roster / Export Failure | Underlying Spreadsheet or HRIS Cause | How OrgLayout Resolves It Locally |
|---|---|---|
| Standard Excel PivotTables only count direct reports (1 layer deep) | A flat `Manager ID` column in Excel only knows who reports directly to a Director (L3), missing all L4 managers and L5 ICs underneath them in a VP’s rollup. | Runs a full recursive tree traversal to compute both Direct Span (e.g., 4) and Total Subtree Rollup Headcount (e.g., 48 HC) and Payroll ($6.84M). |
| Hidden orphan rows and duplicate IDs corrupt FP&A budget totals | If 6 rows have broken Manager IDs or duplicate Employee IDs, recursive formulas either `#REF!` error or silently omit $680K of payroll. | Separates Flagged Discrepancies into a dedicated Quarantine Pool so Mapped Payroll + Quarantined Payroll = 100% of Source Payroll. |
| Micro-managers (1:1 span) and bottleneck layers buried in flat sheets | Flat spreadsheets hide where organizational layers have ballooned to L6 or L7 with single-report managers. | Calculates exact layer depth (`L1..L5+`) and average span of control across the entire organization. |
Frequently Asked by HR Directors, People Ops, and FP&A
How does OrgLayout calculate Direct Span vs. Total Rollup Headcount?
Direct Span counts the immediate direct reports (`children.length`) reporting to a manager. Total Rollup Headcount recursively counts the manager plus all direct and indirect reports across every sub-layer (`L2 -> L3 -> L4 -> L5`) in their reporting tree.
What is included in the 3-sheet Traceable Rollup .XLSX export?
Sheet 1 (`Dept & Manager Rollup`) lists every department head and sub-director with Layer, Direct Span, Rollup HC, Rollup FTE, Rollup Payroll, and exact Source Row ranges. Sheet 2 (`Reconciled Hierarchy`) lists every mapped employee with their full reporting chain path (`L1 -> L5`). Sheet 3 (`Flagged Roster Exceptions`) lists all orphan, duplicate, loop, and zero-FTE rows.
Can I fix orphan managers and circular loops directly in the calculator?
Yes. Click `Assign Manager`, `Deduplicate`, `Break Loop`, `Map to Eng`, or `Set 1.0 FTE` on any discrepancy row (or click `Auto-Quarantine All`) and watch the rollup headcount and payroll equations recalculate live.
Is compensation data ever sent to an external server?
No. All span-of-control and payroll rollup calculations run 100% locally inside your browser tab.
