Final answer:
The path a Case or HR Task takes upon escalation is defined by Escalation Rules, which are a set of predefined criteria that dictate when and how a case should be forwarded to a higher authority.
Step-by-step explanation:
The path that a Case or HR Task will take when it is escalated is defined by Escalation Rules. These rules are a set of criteria that determine when an escalation action is necessary. For example, an escalation rule could specify that if a case has not been resolved within a certain time frame, or if it involves a high-priority client, it should be escalated to a higher-level team member or manager.
Assignment Rules are used to automatically assign new cases to the appropriate user or queue based on predefined conditions. Business Rules help in automating processes by executing specified actions when certain criteria are met. Matching Rules are utilized to ensure records are unique or to avoid duplication. However, for the specific function of dictating the path of an escalated case or HR task, escalation rules are the ones that play the direct role.
