Creating a workflow involves defining the sequence of steps and decision points that guide the flow from start to finish. The elements that can be used in this process include:
* Option C (Events):Events are used to denote something that happens during the course of a process.
They can mark the start, end, or points of change within a workflow, influencing the flow based on occurrences.
* Option D (Gateways):Gateways are decision points that control the divergence and convergence of paths in the process. They determine how the process proceeds based on conditions or events.
* Option E (Activities):Activities represent tasks or work done during the process. They are the primary components of a workflow, outlining the actions that need to be performed.
These elements are fundamental in BPMN for defining and modeling workflows, ensuring clarity and structure in process design.
