You have a model used in an Intuit product surface, such as ranking upgrade offers in TurboTax or prioritizing outreach in Credit Karma. The model team reports a 2% improvement in an offline metric, but product and finance want to know what that means for revenue or contribution margin. Explain how you would connect the model lift to business impact in a way that is credible enough for prioritization.
The model does not create value directly, it changes a decision such as who sees an offer or how items are rankedRevenue impact depends on exposure, conversion, product mix, and retentionMargin impact also depends on variable costs such as support, incentives, refunds, and computeA 2% lift in AUC or precision is not the same as a 2% lift in revenueThe mapping from offline lift to online behavior is often nonlinearDifferent customer segments can have very different economic value
