By explicitly identifying safety-critical functions and hidden failures (like a backup generator or emergency relief valve failing silently), companies can systematically reduce the risk of catastrophic incidents.
This step identifies "functional failures." It outlines the states in which an asset fails to meet its desired performance standard, including total failures and partial failures. 3. What causes each functional failure? sae ja1011 pdf
In what ways can it fail to fulfill its functions? This step identifies the failed states. For example, if the function is to pump 500 gallons per minute, a functional failure could be "fails to pump any liquid at all" or "pumps less than 500 gallons per minute." 3. Failure Modes What causes each functional failure

Intentionally allowing the asset to fail because the cost of prevention outweighs the cost of the failure consequence.
