Evaluate the financial benefit claims for an AI workflow.

All amounts in this fictional monthly review are dollars. Finance verifies that paid overtime fell by $12,000 and vendor invoices fell by $8,000 after an AI workflow change. These are separate expenses. Managers also claim $10,000 of staff capacity, valued at an internal hourly rate; $6,000 of that claim covers exactly the hours responsible for the overtime reduction, while $4,000 covers salaried time with no payroll change. A claimed $20,000 of incremental revenue includes $5,000 shifted from another company product. The transferred $5,000 produces the same contribution as the product it displaced, so its net contribution effect is zero. Finance estimates a 40% contribution margin on the remaining revenue. A concurrent sales campaign means none of the remaining revenue has been causally attributed to AI. Assume no incremental AI costs for this exercise, and do not assume that a before/after expense change establishes AI causality.
