A leader asks whether training paid off, but the team may not have enough source data to isolate training from manager support, workflow changes, tooling, timing, or other business factors.
Look for the decision being made, the costs included, the outcome data available, and whether the learning effort can reasonably be treated as a contributor rather than the only cause.
Before calculating ROI, write what evidence you have, what evidence is missing, and what other factors may have contributed to the result.
Use Excel, Sheets, or Power BI to separate cost, participation, readiness, behavior, workflow, and business-result signals before turning them into one number.
Ask AI to identify what an ROI claim would need to prove, then verify every assumption against approved source data before sharing anything.
