Scenario

U+ Bank is cross-selling on the web by showing various credit cards to customers. Because of each card's credit limits, credit cards are unsuitable for customers if their credit score is less than 300 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 in case the score is not available.

Your assignment consists of the following tasks:

Task 1: Create a scorecard, Determine Credit Score, with exact specifications

Customer Credit Card indicator

Assign a score of 100 if the customer has any card with U+. Otherwise, assign a score of 0.

Note: For this condition, use the HasCards property. The value “Y” indicates the customer does have a card with U+.

Customer Income

Split the values for yearly income into three ranges, and assign scores to each range as follows:

Condition	Score
<=10000	50
<=40000	100
<=75000	150
Otherwise	200

Note: Use the Income property, which shows monthly income, to create an expression that determines yearly income.

Customer Age

Split the values for age into four ranges, and assign scores to the age ranges as follows:

Condition	Score
<=18	0
<=25	50
<=40	100
<=50	150
Otherwise	200

Note: For this requirement, use the Age property.

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

The scorecard should output Not Suitable if the credit score is less than 300 and Suitable if the score is equal to or higher than 300.

Task 3: Confirm your work

Verify the scorecards for customers Troy and Robert.
