MNT.3:2 - Problem

Observation, diagnosis and consequence are easily collapsed. A high vibration value is an observation under particular measurement conditions. A damaged bearing is a condition claim. A lubrication mechanism is a causal explanation. Loss of district-heating service is a possible System-level consequence. Evidence supporting one does not automatically support the others.

Maintenance history adds another ambiguity: a removed component may have failed, been replaced preventively or been removed because another fault was suspected. Counting all removals as failures can change a policy for the wrong reason.
