Having 15 years in tech consulting and now use various LLM for programming and management. So this a proven playbook for CFO and CTO how to reduce vendor dependency and automate delivery
Decided to systematize my experience on how headcount can be changed so I ran numbers for a 100-person program (10 onsite senior devs/architects, 50 offshore devs, 25 QA, 5 BAs, 8 PMs, 2 program managers).
Claude AI Replacement:
- 20 Claude agents replace 50 offshore devs
- 15 QA/BA tasks automated, humans retained for edge cases
- PM automation handles ~30–40% of workload
Budget Impact:
- Original cost: $13.7M/year
- New cost with Claude: $6.5M/year → $7.2M savings (~53%)
Productivity / Quality:
- Bug fixing & refactoring: 2–2.5× human throughput
- New feature dev: 2× human
- TDD/automated tests: 2× human coverage
- Quality matches or exceeds mid-senior offshore engineers
Claude AI + retained humans = lower cost, higher throughput, strong TDD/testing, multi-file refactors, and still keeps humans for edge-case judgment.
