The fix controls you, you do not control the fix. The basic strategy is totally reactive. This is a time-based maintenance strategy. On a predetermined periodic basis, equipment is taken off-line, opened up, and inspected.
Some preventive maintenance is necessary.
For example, various state laws require that annual boiler inspections be conducted. This is a condition-based maintenance strategy. This is a much more economically feasible strategy as labor, materials and production schedules are used much more efficiently. This is a concept of the future, though not any revelation. The concept is that if we did our jobs with a mastery level of precision, then the only failures we would have, would be wear-out failures.
