MNT.Preface:7 - Assumptions, costs and limits

The principal examples concern industrial equipment and draw some bounded protection and human-performance lessons from aviation. They do not establish a universal transfer to software services, nuclear facilities or every other maintenance setting. An application needs the equipment’s failure and operating basis and its actual current protection rules.

The language favours explicit supported claims. That can reveal an uncertainty that an informal plan concealed. It can also save investigation or paperwork when a smaller answer is sufficient. Its expected contribution is better maintenance reasoning and fewer unsupported transitions, not a guaranteed decrease in failures, cost or exposure.

All application names, observations, quantities and outcomes in this edition are constructed. They make the reasoning inspectable; they are not evidence that the framework has improved an actual plant. A measured-effect claim requires its own population, comparator, observation and causal basis.
