What article is used to identify critical maintenance tasks?

The article often referenced for identifying critical maintenance tasks is the "Failure Mode and Effects Analysis" (FMEA). FMEA helps in systematically evaluating potential failure modes within a system, their causes, and effects on operations. By prioritizing these failures based on their severity, occurrence, and detectability, organizations can identify and focus on the most critical maintenance tasks necessary to mitigate risks and ensure operational reliability.
