# Managing Headcount Planning

Structures workforce planning with headcount budgeting, compensation modeling, and organizational analysis for FP&A, management accounting, and business intelligence teams.

## When To Use

- Annual or quarterly headcount budgeting cycles
- Scenario modeling for hiring plans (expansion, contraction, reorg)
- Compensation benchmarking and total cost-of-employment analysis
- Departmental workforce reviews or org structure assessments
- Board or leadership presentations requiring workforce cost projections
- M&A integration headcount planning or post-acquisition rationalization

## Inputs To Gather

- **Current roster data**: Employee census with department, title, level, location, start date, and FTE status
- **Compensation details**: Base salary, bonus targets, equity grants, commission structures per role
- **Burden rate assumptions**: Benefits cost per employee, payroll taxes by jurisdiction [VERIFY], employer 401(k)/pension match, insurance premiums
- **Hiring plan**: Open requisitions, target start dates, recruiting pipeline stage
- **Attrition data**: Historical voluntary/involuntary turnover rates by department and level
- **Budget constraints**: Total comp envelope, approved headcount cap, cost-center allocations
- **Org chart**: Reporting structure, span-of-control metrics, leveling framework

## Workflow

1. **Build the current-state roster model**
   - Import employee census and map each record to cost center, department, and level
   - Attach fully loaded compensation: base + bonus + equity + benefits burden + payroll tax
   - Calculate current-state run-rate (annualized) and monthly cash outflow by department
   - Flag any missing data fields (e.g., no bonus target, missing location) with [VERIFY]

2. **Layer in planned changes**
   - Add approved new hires with assumed start dates, ramp periods, and target compensation
   - Model backfills for projected attrition using historical turnover rates
   - Apply planned promotions, merit increases, and equity refresh grants with effective dates
   - Account for known departures, RIFs, or contractor-to-FTE conversions

3. **Run scenario analysis**
   - **Base case**: Approved plan with current assumptions
   - **Upside case**: Accelerated hiring, lower attrition, or expanded roles
   - **Downside case**: Hiring freeze, elevated attrition, or budget reduction
   - For each scenario, produce monthly headcount and cost projections over the planning horizon (typically 4-8 quarters)
   - Calculate variance between scenarios to quantify decision impact

4. **Analyze organizational metrics**
   - Span of control by manager level (flag ratios below 3:1 or above 12:1)
   - Revenue per employee and cost per employee by business unit
   - Compensation mix analysis (base vs. variable vs. equity) against market benchmarks [VERIFY]
   - Location cost arbitrage opportunities (if multi-geography)

5. **Prepare the headcount plan deliverable**
   - Summary dashboard: total headcount, total cost, quarter-over-quarter delta
   - Department-level detail: HC by level, average comp, open req count, projected attrition
   - Scenario comparison: side-by-side cost and HC for each scenario with key assumptions noted
   - Sensitivity table: impact of +/- 10% attrition, +/- 5% comp inflation, or delayed start dates

## Output

The deliverable is a **Headcount Plan Report** containing:

- **Executive summary** with total HC, total fully loaded cost, and net change vs. prior period
- **Roster-level detail** by cost center with per-employee loaded cost (anonymized if needed)
- **Monthly projection table** showing HC and cost trajectory for the planning horizon
- **Scenario matrix** with base/upside/downside cases and key variance drivers
- **Org health metrics**: span of control, comp mix, revenue-per-head, attrition assumptions
- **Open items log** listing all [VERIFY] flags, missing data, and pending leadership decisions

## Quality Checks

- Confirm total loaded cost ties back to GL actuals for the most recent closed period within a 2% tolerance
- Verify headcount totals reconcile to HRIS system of record — every FTE and contractor is accounted for
- Ensure burden rate assumptions (benefits, taxes) reflect current plan year rates [VERIFY against benefits renewal and jurisdiction-specific payroll tax tables]
- Validate attrition assumptions against trailing 12-month actuals; flag if projected rate deviates by more than 20%
- Check that new hire compensation aligns with approved salary bands and leveling framework
- Confirm scenario assumptions are internally consistent (e.g., a hiring freeze scenario should not include new-hire costs)
- Review for double-counting: backfills should not overlap with existing employees still on roster
- Ensure all currency, FTE basis (annualized vs. monthly), and date conventions are consistent throughout
