Which of the following is NOT a type of maintenance trigger?

Immediate Trigger is not a recognized type of maintenance trigger in the context of maintenance management. In maintenance management, triggers typically refer to specific events or conditions that prompt maintenance activities.

Local Trigger and Global Trigger are categorized based on their scope. A Local Trigger pertains specifically to maintenance needs identified within a localized area or system, often related to specific equipment or operations. On the other hand, a Global Trigger suggests a broader concern that could affect an entire facility or multiple systems, indicating that maintenance actions need to be taken on a larger scale.

Scheduled Trigger refers to maintenance activities that are predetermined based on time intervals or usage metrics. This type of trigger is often part of a preventive maintenance program where tasks are carried out regularly to ensure optimal functionality.

By understanding these categories, it becomes clear that Immediate Trigger does not fit within established frameworks used in maintenance literature and practice, which focus on planned, reactive, or periodical maintenance triggers rather than a singular, immediate response based on an unspecified instantaneous need.
