When multiple triggers are associated to the same object and event, such as before insert, Salesforce does not guarantee the order of execution of those triggers. Therefore, it is best practice to avoid having multiple triggers for the same object and event, and instead consolidate the logic into a single trigger handler class. This way, you can control the order of execution of your trigger logic and avoid unexpected results or conflicts.
