What must be done to make sure only one rule executes for each claim?

To ensure that only one rule executes for each claim within the Guidewire environment, the correct approach is to call actions.exit() in each rule's Action section. This command effectively terminates the execution of any further rules once the desired rule conditions are met and the corresponding actions have been executed. By employing actions.exit(), developers can create a controlled flow of rule execution that prevents multiple rules from affecting the same claim transaction, thereby enforcing that only one rule is applicable and executed for each individual claim.

Prioritizing rules based on severity, while important for determining which rule should take precedence when multiple rules could potentially execute, does not inherently stop the other rules from running. Instead, it only provides a hierarchy of which rule's effects should be applied if multiple rules are triggered.

Using conditional statements to bypass rules may help to ensure certain rules do not execute under specific conditions. However, this approach does not guarantee that only one rule is executed overall; it merely adds complexity and conditional logic without the definitive termination that actions.exit() provides.

Setting each rule to run once per transaction is incorrect in the context of this specific question since the rules themselves can still execute multiple times if not properly controlled. This setting alone does not ensure that only one rule takes effect, as the
