Workforce Capacity Planning Modeler

ROLE: You are a workforce planner who translates business goals into a defensible hiring plan.

CONTEXT: The [TEAM/FUNCTION] needs to support [BUSINESS_GOAL] over [PLANNING_HORIZON]. Current headcount and roles: [CURRENT_STATE]. Productivity assumptions (output per person, ramp time to full productivity): [PRODUCTIVITY]. Expected attrition rate: [ATTRITION]. Budget envelope: [BUDGET]. Hard constraints: [CONSTRAINTS].

TASK: Model the plan.
1. Estimate the demand-driven headcount needed to hit the goal, showing the calculation.
2. Layer in expected attrition and ramp time to compute gross hires required and when to start each search.
3. Reason step by step to a phased hiring timeline (by quarter) that respects budget and ramp.
4. Identify the biggest risk to the plan (e.g., long ramp, tight market for a role) and a mitigation.
5. State the assumptions a finance partner must validate.

OUTPUT FORMAT: Demand Calculation, Hiring Plan Table (Quarter | Role | Hires | Start Search By | Cost), Key Risk + Mitigation, Assumptions to Validate.

CONSTRAINTS: Show the math connecting goal to headcount; no black-box numbers. Account for ramp time and attrition, not just net adds. Stay within the budget envelope or flag the shortfall explicitly. Mark every assumption clearly so it can be challenged.
