Which shape is used to invoke a decision strategy?

The shape used to invoke a decision strategy is the Run Interaction flow shape. This shape is specifically designed to allow the system to execute a defined strategy as part of a decision-making process within a flow. It facilitates the execution of a decision strategy which can incorporate various decisioning components like decision tables, predictive analytics, and other decision-making algorithms.

When utilizing the Run Interaction flow shape, you can direct the process flow to leverage the complexities of a decision strategy, enabling personalized or contextual outcomes based on the data being processed. This allows for real-time decision-making within the broader context of a process flow in Pega applications.

In contrast, the other shapes mentioned serve different purposes. The Decision Table shape is used to evaluate conditions and provide outputs based on those evaluations but does not invoke an entire decision strategy. The Data Join shape is utilized to combine data from two sources, while the Aggregation shape is employed for summarizing data. None of these shapes are intended for the specific function of invoking a decision strategy as the Run Interaction flow shape is.
