How many decision gateways would be shown on the activity diagram for the task of checking an order?

The task of checking an order typically involves evaluating various conditions that dictate the next steps in the process. For instance, a decision gateway might be utilized to determine if the order is complete, if it meets certain criteria for processing, or if any issues such as discrepancies or missing information exist.

Given that the task could require multiple checks—such as verifying customer details, confirming product availability, and assessing payment status—it is reasonable to represent these decision points as gateways in the activity diagram. Each of these checks effectively creates a fork in the process, leading to different outcomes based on the conditions evaluated.

Therefore, having two decision gateways would align well with the complexity of the order-checking process, capturing the necessary decision-making conditions without overwhelming the diagram. This setup allows for a clear visual representation of the process where multiple decisions need to be made based on the state of the order.
