Plan headcount with demand drivers and capacity limits. Compare scenarios, seasonality, and service-level buffers easily. Export results, align budgets, and brief leaders with confidence.
Use the workload model when demand is expressed as tickets, calls, cases, or tasks per month. The driver is scaled by growth and monthly seasonality indices (Jan–Dec). A 1.20 index means 20% more demand than baseline, while 0.85 means a softer month. This structure supports scenario testing for product launches, marketing spikes, and policy changes without rewriting the model.
Effective capacity is calculated from hours per FTE per month, utilization, shrinkage, and overtime uplift. For example, 160 hours × 85% utilization × (1 − 15% shrinkage) yields 115.6 productive hours before overtime. If average handle time is 6 minutes, one FTE can complete roughly 1,156 units monthly. Small changes in shrinkage often move staffing more than growth does, so validate meeting load and training time.
Headcount planning includes expected leavers using annual turnover divided across months. If turnover is 12% annually, the implied monthly rate is 1%. The table shows start headcount, leavers, and hires needed to reach the target. Recruit-by dates back-plan from time-to-fill (days converted to months). Fully productive timing uses ramp-up weeks; ramp productivity adjusts external hiring volume so you can budget realistic onboarding load.
Two levers manage uncertainty: buffer percentage and confidence multiplier. Buffer covers operational volatility like incident response, backlog recovery, and absence variability. Confidence converts service risk into a simple coverage factor (for example 80% → 1.05×). Together they prevent systematic under-hiring when demand estimates are optimistic. Keep buffers smaller for stable work, and higher for seasonal, regulated, or customer-facing operations.
Read the forecast table as a monthly hiring target, not a single hiring event. Peak headcount highlights the most constrained month, while average FTE supports budget baselines. Compare current capacity (employees plus contractor FTE) to average demand to quantify the gap. Use internal fill rate to coordinate mobility plans. Export CSV for workforce reviews, and export PDF for leadership updates and budget sign-off. When testing scenarios, change one variable at a time, record peak headcount deltas, and agree thresholds that trigger hiring, redeployment, or temporary contractor coverage actions earlier.
Workload uses handle time and productive hours to convert units into FTE. Ratio uses a coverage rule like customers per employee. Choose workload for operational queues and ratio for account portfolios, stores, or seat-based programs.
Start with the last 12 months of volume by month, divide each month by the annual average, then normalize so the average index equals 1.0. Keep values between 0.2 and 3.0, and revisit after major process changes.
They determine effective productive hours. Meetings, training, PTO, and quality work reduce time available for delivery. A 5‑point increase in shrinkage can remove several productive hours per FTE monthly, raising required staffing even if demand stays flat.
Time-to-fill is converted into lead-time months to generate recruit-by guidance. Ramp-up adds a fully productive date and a ramp productivity adjustment for external hires. Use these fields to coordinate recruiting capacity, onboarding cohorts, and manager availability.
Contractor coverage is treated as FTE and subtracts from demand before converting to employee headcount. This helps compare mixed models. If contractors are less productive than employees, reduce contractor FTE or increase buffer to represent the productivity difference.
Yes. Run separate scenarios for each role, region, or queue so assumptions stay consistent. Export CSV and combine results in your planning spreadsheet. For shared recruiting pipelines, align start dates and use the peak months to stage hiring waves.
