Final answer:
The property automatically recomputed for each proposition after a change in prioritization rule is Priority. It orders propositions according to new business rules or strategies regardless of their individual scores.
Step-by-step explanation:
When a Strategy Designer makes a change to a decision strategy to implement a new prioritization rule, the property that is automatically recomputed for each proposition is C) Priority. In decision strategy design, priority determines the order in which propositions are considered and potentially presented to customers. As opposed to rank or propensity, which classify propositions based on their value or the likelihood of a customer accepting them, priority is used to enforce business rules that might dictate the order of propositions irrespective of their individual scores.
For example, if a business decides that certain products should always be offered before others during a particular campaign, the priority rule could be set to reflect this, ensuring that propositions are aligned correctly with the new campaign strategy. This approach enables businesses to dynamically adapt to changing market conditions or business objectives.
