Testing and measuring better strategies across the lending lifecycle. Lending teams have more data and more ways to optimize than ever, but knowing what actually drives better outcomes requires experimentation. A new acquisition channel can bring in more customers while worsening credit quality. A tighter approval rule can lower losses while turning away profitable borrowers. A collections campaign can improve short-term payments without changing eventual recoveries. These trade-offs are difficult to see without disciplined testing. This panel examines how lenders design experiments across acquisition, underwriting, pricing, line management and servicing; choose the right measures; and separate a strategy’s effect from changes in the economy or the borrower mix.
