Scenario

U+ Bank wants to improve the experience of its customers with personalized decisions that are driven by customer-centric engagement policies and predictive models. After an initial data mapping exercise, U+ Bank confirms that the Pega financial data model is a great match.

The project team sets up the implementation application of Pega Customer Decision Hub™ by using the setup wizard.

As a decisioning architect, your role is to review the data model that the wizard sets up and perform a gap analysis by leading a data mapping workshop with the stakeholders.

As the output of the gap analysis, the project team identified the need to make the following extension to the customer entity:

  • A new offline scores entity and properties to hold U+ Banks offline model scores. This new entity has a one-to-one relationship with the customer class that the U+ Bank data science team maintains.

As the decisioning architect, first, capture the requirements into the Pega Financial Services xCAR data model and work with the system architects to extend the data model in Customer Decision Hub.

Use the following credentials to log in to the exercise system:

Role User name Password
System architect SystemArchitect rules
Decisioning architect DecisioningArchitect rules

Your assignment consists of the following tasks:

Task 1: Download the data model documentation

As a decisioning architect, download the Financial Services Customer Analytical Data Model documentation from Pega Marketplace.

Task 2: Review and extend the data model documentation (optional)

As a decisioning architect, review the downloaded data model and capture the following requirements to the Pega Financial Services xCAR data model XLSX file. Update the documentation and add a new OfflineScores entity and the following properties:

Attribute Description Update frequency Type Notes

CustomerID

Unique Customer identifier that is mapped to the CustomerID in the customer class.

Updated monthly

Text

The column name is CustID

ChurnScore

A churn score model that the U+ Bank data science team prepared. Indicates the churn score of the customer, a number between 0-100.

Updated monthly

Integer

 

CardScore

An offline score that represents the interest of the customer to credit card products (0 to 1).

Updated monthly

Decimal

 

MortgageScore

An offline score that represents the interest of the customer to mortgage products (0 to 1).

Updated monthly

Decimal

 

InsuranceScore

An offline score that represents the interest of the customer to insurance products (0 to 1).

Updated monthly

Decimal

 
Caution: For the purposes of the exercise, this task is added to raise awareness. There is no integration between the XLSX file and the Pega data model. The changes made in the XLSX file are for documentation purposes and help you understand the existing data model.

Task 3: Add and map a new data class

As a system architect, create a new data class: UBank-Data-OfflineScores. Associate the new class with the OfflineScores database table and create the documented properties.

Note: In a real-life scenario, the database team typically creates the database. For the purposes of this exercise, the OfflineScores table already exists in the database for you.

Task 4: Create a new data set

As a decisioning architect, create a new OfflineScores data set to access the OfflineScores table.

Task 5: Add OfflineScores data source to allow list

As a decisioning architect, extend the customer data model with the newly defined offline model scores by using Customer Profile Designer.

 

You must initiate your own Pega instance to complete this Challenge.

Initialization may take up to 5 minutes so please be patient.
