Act as a senior FP&A business partner specializing in workforce and operating-capacity planning.

Develop an OPEX, headcount, and variable-capacity plan using the information provided below.

Organization or function:
{{organization_function}}

Planning horizon:
{{planning_horizon}}

Demand and workload forecast:
{{demand_forecast}}

Current workforce and capacity:
{{current_capacity}}

Compensation and operating-cost assumptions:
{{cost_assumptions}}

Service-level and productivity requirements:
{{service_requirements}}

Known constraints:
{{constraints}}

Analysis requirements:

1. Translate the demand forecast into workload by month or quarter.
2. Define the capacity unit appropriate to the function, such as:
   - productive hours;
   - transactions;
   - cases;
   - production units;
   - customer contacts;
   - projects; or
   - service locations.
3. Calculate required capacity using:
   - workload;
   - productivity;
   - utilization;
   - shrinkage;
   - absenteeism;
   - training;
   - leave;
   - overtime;
   - vacancy;
   - attrition; and
   - service-level assumptions.
4. Separate workforce into:
   - permanent employees;
   - fixed-term employees;
   - contractors;
   - outsourced capacity;
   - overtime;
   - temporary labor; and
   - automation-supported capacity.
5. Model:
   - opening headcount;
   - hires;
   - attrition;
   - transfers;
   - promotions;
   - vacancies;
   - average headcount;
   - closing headcount;
   - fully loaded cost; and
   - productivity.
6. Separate OPEX into fixed, variable, semi-variable, step, and one-time categories.
7. Build base, high-demand, and low-demand scenarios.
8. Identify capacity gaps, excess capacity, hiring lead times, and service risks.
9. Compare alternatives such as hiring, overtime, contractors, outsourcing, process improvement, and automation.
10. Quantify cost, speed, flexibility, risk, and service implications of each alternative.
11. Prevent double counting between headcount cost, contractor cost, overtime, and outsourced capacity.
12. Do not invent labor law requirements, salary rates, productivity standards, or service assumptions.
13. Identify items requiring HR, operations, legal, procurement, or management validation.

Present the result as:
{{output_format}}

Include:
- demand-to-capacity model;
- workforce movement schedule;
- monthly or quarterly headcount plan;
- fully loaded personnel-cost budget;
- non-personnel OPEX plan;
- scenario comparison;
- capacity gap analysis;
- workforce-mix options;
- risks and constraints;
- validation questions; and
- recommended staffing and capacity actions.

Customization Variables

Replace each variable shown in double curly brackets with accurate information from your own professional context.

{{organization_function}}

Organization or Function

Required

Example: Example: Customer support operations

Identify the business unit, department, or operation being planned.

{{planning_horizon}}

Planning Horizon

Required

Example: Example: Monthly for the next 18 months

State the period and planning frequency.

{{demand_forecast}}

Demand and Workload Forecast

Required

Example: Provide forecast volumes, workload, customer demand, projects, or production requirements.

Demand should be stated in measurable workload units.

{{current_capacity}}

Current Workforce and Capacity

Required

Example: List headcount, roles, productivity, utilization, shifts, contractors, vacancies, and capacity.

Include both internal and external capacity.

{{cost_assumptions}}

Compensation and Operating-Cost Assumptions

Required

Example: Provide salary, benefits, overtime, contractor, facilities, technology, and support-cost assumptions.

Use fully loaded cost assumptions where available.

{{service_requirements}}

Service-Level and Productivity Requirements

Required

Example: Describe response times, quality targets, productivity, utilization, and coverage requirements.

Capacity requirements depend on both volume and expected service levels.

{{constraints}}

Known Constraints

Optional

Example: Include hiring lead times, labor availability, shift limits, budgets, systems, and facility capacity.

Constraints help prevent unrealistic staffing plans.

{{output_format}}

Output Format

Required

Choose the format required for budgeting, review, or implementation.

🎯

Task

Requires translation of workload into headcount, capacity, OPEX, and workforce-mix decisions.

🛡️

Constraints

Prevents double counting and invented labor, salary, productivity, or legal assumptions.

📚

Output Structure

Requires capacity models, workforce schedules, OPEX plans, scenarios, gaps, and actions.

🔑

Input Variables

Organization, horizon, demand, capacity, cost assumptions, service requirements, constraints, and output format.

Improve the Result

Customization Tips

  1. Use workload and productive hours rather than simple headcount ratios.
  2. Include hiring lead time, attrition, training time, and expected vacancy periods.
  3. Separate permanent, temporary, contractor, outsourced, and overtime capacity.
  4. Define service levels so the model does not optimize cost at the expense of required performance.
  5. Ask for monthly workforce movements when the plan will feed payroll and recruitment schedules.
