Which empirical transfer test must precede deploying a predictive model across cohorts?

Transfer questionWhy it matters
Is the outcome defined the same way?“Defection” and “profitability” can have different boundaries
Is the observation horizon comparable?Short-term buying and long-term value are not interchangeable
Are the input variables available before the action?A post-outcome signal cannot support a pre-outcome intervention
Is the cost boundary comparable?Revenue, margin, and profit can reverse a priority
Is the decision use the same?Prediction for triage is not prediction for treatment
