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 1:1 Financial Services 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 Insights Cache:

• A new Offline Product Scores entity and properties to hold the offline product scores for U+ Bank. This new entity has a one-to-many relationship with the customer class that the U+ Bank data science team maintains.

As the Decisioning Architect, first, capture the requirements into the 1:1 Financial Services Data Model and work with the system architects to extend the Customer Insights Cache. Then, extend the customer profile with the newly defined entity.

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