Overview

Loans domain specifics

There is a concept of customer’s credit-score with essential impact on the pricing and availability of loan products to individual customers. The basic idea is the ability to define and execute business rules to calculate interest rate, min-max loan amount and min-max loan term for a particular customer based on the customer’s current credit-score, purchased subscription and redeemed engagement benefits.

The customer’s credit-score is calculated and managed by the Risk domain. Integration with the Risk domain’s services is in scope of Loan Manager service capabilities.

Product Manager takes the credit-score as one of the input parameter’s provided by Loan Manager to evaluate the availability and pricing of loan products.
