To ensure that the Gold credit card offer is presented only to customers who have an annual income of more than USD 150,000, you need to configure an engagement policy condition in the Next-Best-Action Designer.
Here's why:
* Engagement Policy Condition:
* Engagement policies in the Next-Best-Action Designer are used to define conditions that determine whether a particular action (such as offering a Gold credit card) is suitable or eligible for a customer.
* By setting an engagement policy condition based on the customer's annual income, you ensure that only those customers who meet the specified income threshold are eligible to receive the offer.
* This condition acts as a filter that evaluates each customer's income and includes only those who earn more than USD 150,000.

* Defining Property Constraint:
* A property constraint can be used to limit the number of VISA card offers sent in an outbound run.
* This constraint is based on the card_type action property, ensuring that only a specified number of VISA card offers are included.
* This method allows for precise control over the types of actions being sent, adhering to business requirements.

To re-implement the requirement using the always-on outbound customer engagement paradigm, configure the primary schedule to run daily and let the AI choose the best action from all the actions that a customer qualifies for based on engagement policies. This approach leverages AI to dynamically select the most relevant next best actions, ensuring timely and personalized customer interactions.

Understanding Volume Constraints:
* Volume constraints can be applied to limit the number of actions offered to customers.
* Constraints can be set to apply to actions as a group or individually.
Scenario Analysis:
* In the given scenario, a customer qualifies for three actions.
* The top-ranked action has not reached its volume limit, but the lower-ranked actions have.
* Since the constraints are applied as a group, if the top-ranked action is available, it will be selected.
* The lower-ranked actions, having reached their limits, will not be selected.
Conclusion:
* Only the top-ranked action will be selected for the customer in the outbound run.

Updating Scorecard in Decision Strategy: When a scorecard rule is updated to include a new property such as customer income, it is essential to reflect this change in the decision strategy. The scorecard properties must be correctly mapped to ensure the new calculations are utilized.
