How to Verify AI Productivity Case Studies Before Using Their Numbers in Your ROI
Recent OpenAI case studies report that Asana used Codex to remove Enzyme in about two weeks with roughly $12,000 in model and infrastructure cost, while NVIDIA participants describe a ChatGPT Work process saving about 16 hours per week and another workflow turning 25 to 40 external updates into 5 to 8 actionable signals. These are observed results from specific organizations, people, tasks, and vendor-published case studies. They are not transferable ROI guarantees. A team should reconstruct the original baseline, define one reversible task, record human review and rework, include model and infrastructure cost, and compare accepted outcomes against the same non-AI or historical standard before expanding deployment.
