Your Reliability Engineering Professional Development Site
Applied Reliability explores how engineering, maintenance, asset integrity and risk management principles can be translated into practical business decisions. Through real-world examples, case studies, and analytical methods, the series demonstrates how organizations can improve reliability, reduce risk, optimize maintenance strategies, and enhance asset performance.
If maintenance work planning is a production line, then the planner is neither a firefighter nor a dispatcher.
The perfect maintenance planner is a design engineer for executable work.
They enable perfect execution. They hand over readiness, not problems.

Special problems require specialist tools.
In RCM, we assign fault-finding tasks to hidden failures. But what happens when the hidden problem is embedded in the maintenance strategy itself?
Reliability models are not universally interchangeable. Getting the right answer depends on choosing the correct mathematical framework for the problem, and using the wrong approach leads to false confidence, wasted budgets, and costly operational errors.

Many industries are using this formula to manage Multi-Million-dollar assets:
MTBF = Total Operating time ÷ Number of failures
Simple. Easy. Dangerously incomplete.
Simple arithmetic MTBF assumes failures are Random and Constant. It treats asset health as Static.
But real-life industrial assets are not static. Failure rates are not constant.
Assets age. Lubricants degrade. Corrosion accelerates. Fatigue accumulates. Failure rates begin changing long before catastrophic breakdown occurs.
