Szenario

A financial institution offers various credit cards to customers. Because of the limit for each card, credit cards are unsuitable for customers if their credit score is less than 600 due to the likelihood of default.

The credit score value is available in the data model, and external processes populate the value in a nightly batch. However, a credit score is not computed for every customer.

As a result, the business wants a scorecard that computes a customer's credit score if the score is not available.

Condition	Score
<=7000	0
<=8000	100
<=10000	150
<=12000	200
Otherwise	300

Split the values for Debt To Income Ratio into three ranges, and assign scores to the ranges as shown in the following table:

Condition	Score
<=20	300
<=30	200
<=40	100
Otherwise	50

Task 2: Configure the scorecard result to Not suitable and Suitable

The scorecard outputs Not Suitable if the credit score is less than 600 and Suitable if the score is equal to or higher than 600.
