An engagement like this is scoped against a target of 30-45% reduction in manual underwriting hours - a planning assumption built from your own application volumes during scoping, not a promise. Those hours become capacity for relationship management and complex cases; no one gets replaced, and the routine-decision queue stops setting the pace. Origination cycle time is the second planned gain, because scoring that once waited on manual data compilation happens at application time - and faster time-to-close recovers deals that currently leak to quicker lenders. Credit-loss improvement and lower BSA/AML false-positive volume are modeled during scoping from your own portfolio and alert data, not borrowed from someone else's institution.
The return should compound over the 12-month post-deployment cycle: labor capacity and deal recovery arrive first, then credit-loss and compliance-rework improvements show up in the P&L as the model accumulates outcome data. Institutions that extend the system to portfolio management and risk-based pricing have a further lever on net interest margin. Every figure in the business case is built during scoping from your origination costs, loss history, and deal volumes - a modeled projection, not a claimed client result.
