FTE Capacity Sizing

Translate any agency scope — SOW, retainer, campaign brief, or informal request — into a concrete staffing model with role-by-role FTE allocation, utilization analysis, seniority validation, and financial viability assessment against the proposed fee.

The 70/30 Operating Model

This skill operates on a foundational principle: 70% of agency task volume is handled by AI agents (Claude skills, MCP flows, automated pipelines) and 30% requires irreducible human judgment, creativity, and relationships. This is not aspirational — it is the operating assumption built into every calculation.

What this means in practice:

• A deliverable requiring 8 gross hours doesn't need 8 human hours — it needs 8 × (1 - AI rate) human hours
• A monthly report with 85% AI automation needs only 1.2 human hours (AI generates the report, a human reviews and presents)
• A creative concept with 20% AI rate still needs 12.8 human hours of 16 total (creativity remains human-led)
• The FTE count reflects the human core, not the full task volume
