What is true about the execution of an XOR gateway?

• A. It can execute multiple outgoing flows
• B. It can execute one outgoing flow only
• C. It waits for all flows to complete
• D. It executes based on the first incoming flow

Answer: (B)

When considering the XOR (exclusive or) gateway, it is designed to facilitate decision-making in a process model. The key characteristic of an XOR gateway is that it is meant to evaluate multiple incoming flows and determine a single outgoing flow based on defined conditions. Therefore, it will only execute one outgoing flow at a time. The logic behind this is rooted in the nature of the XOR gateway, which is built to create exclusive pathways in process flows. When the process reaches an XOR gateway, it examines the conditions associated with the incoming flows and triggers only the path that meets the criteria. The other paths are not considered, thereby ensuring that exactly one outgoing flow is activated. This pathway exclusivity makes the XOR gateway particularly useful for scenarios where only one action should occur based on specific criteria, ensuring clarity and simplicity in managing process flows. Understanding this concept is essential for designing efficient workflows, as it defines how decisions are structured in process models using XOR gateways.
