Which feature allows developers to define conditions for executing different paths in a process flow?

The feature that allows developers to define conditions for executing different paths in a process flow is the decision shapes. Decision shapes facilitate logical branching in the process flow based on specified conditions. When implementing a process, developers can use decision shapes to evaluate certain criteria, which determines the route the process will take. For example, if a decision shape evaluates a data value against a threshold, it can direct the flow either down one path or another, allowing for dynamic and responsive process execution based on runtime data.

In contrast, the other features listed serve different purposes. Data pages are used for managing and accessing data efficiently within Pega applications but do not facilitate conditional logic within process flows. Service level agreements define performance targets and goals for completing tasks but do not dictate flow paths. Integration connectors are used for connecting and exchanging data with external systems rather than controlling flow within a process. Each of these components plays a vital role within Pega, but decision shapes are specifically designed for the purpose of conditionally directing process flows.
