Which gateway is used most frequently?

The XOR (exclusive OR) gateway is widely recognized as one of the most frequently used gateways in process modeling because it facilitates decision-making based on conditions or criteria. This gateway allows the process to split into multiple paths but ensures that only one of those paths is taken at any given time. This behavior is essential in many business processes where a specific condition must dictate the flow of the process.

The functionality of the XOR gateway supports clear, singular decision points, which makes it easier for modelers to design processes where only one outcome is required based on given inputs. This encapsulates typical business logic scenarios, such as approving a request or selecting between options where only one can logically apply.

Other types of gateways, such as the AND and OR gateways, have distinct uses but are not as commonly utilized for general decision-making in process flows. The AND gateway allows all designated paths to be followed simultaneously, and the OR gateway could lead to multiple paths being taken, which might complicate the process flow if only one outcome is desired. The Complex gateway is used for more intricate conditions which may not be as frequently necessary as the straightforward decision-making provided by the XOR gateway.

Understanding the proper application of these gateways and the tendency to use XOR for clear, single-path decisions is
