Each area stands alone as a mandate. Most books need more than one, and the sequence usually reveals itself in the first four weeks.
The book you already own is the cheapest growth.
What it moves →Pay for booked accounts, not leads.
Channel design and economics. Pay-for-performance structures for DSAs, brokers and digital partners, built so payout tracks credit quality rather than application volume. Pre-qualification and lead scoring at the top of the funnel, so acquisition spend follows applicants you will actually approve. Full-funnel attribution from spend through to a performing account.
Approve more of the customers you are declining for the wrong reasons.
Credit policy design and rebuild. Application and behavioural scorecard development and validation. Cash-flow underwriting on open-finance data for thin-file and new-to-credit segments. Independent assessment of bureau performance on a genuinely forward-looking application population. Portfolio diagnostics and vintage analysis.
The book you already own is the cheapest growth available to you.
Line increase and decrease programmes run continuously against risk and utilisation rather than as an annual exercise. Proactive repricing. Activation and utilisation campaigns for dormant and low-engagement accounts. Retention and offer design against customer lifetime value. Attrition propensity modelling. Collections strategy driven by propensity to pay and to cure rather than days-past-due bands alone.
Value the decision before you make it.
NPV models for account-level decisioning, applied at origination, at limit and pricing decisions, at retention offers and at portfolio interventions. Risk-based pricing frameworks that move the institution away from a single aggregate price. Champion-challenger design and test-and-learn measurement architecture — including the governance that lets a test run long enough to produce a meaningful result.
A policy you can change in a week, not a quarter.
Decision engine selection, specification and implementation oversight. Open finance integration and the attribute layer that turns raw transaction data into decision-ready variables. Portfolio execution capability. Model deployment, monitoring and refresh. AI applied where it earns its place — income verification, document intelligence, credit operations, collections treatment, agent assist, underwriting automation.
AI is a tool. Credit economics is the discipline.
