From Outage to Judgment
A single outage is an anecdote; a pattern of outages is a verdict. The individual event tells you what broke once, but the sequence of events over years tells you how an operator thinks, spends, and learns, and that is what you are actually buying or regulating. Recurrence is the strongest signal in the whole field: the same failure mode twice is not bad luck, it is an uncorrected decision. Turn the reading skill into a position by asking whether failures are diverse and declining, which marks a maturing operator, or clustered and repeating, which marks one that patches symptoms. Do that and an outage history becomes a due-diligence instrument as sharp as any financial statement.

Why is a repeated failure mode a stronger negative signal than a single severe outage?
Show the answer
A single severe outage can be a genuine one-off or an unusually deep trigger meeting an otherwise sound facility. A repeated failure mode proves the operator saw the problem, wrote a postmortem, and still did not fix the underlying cause, which reveals either a structural constraint they cannot address or a culture that treats symptoms rather than causes. Recurrence converts uncertainty about competence into evidence of it.
