What Asset Criticality Is and How to Rank It
Asset criticality ranks equipment by the consequence of failure so you can focus maintenance where it matters. Here is how to score it, build a criticality matrix, and a scorer.
How to Calculate MTBF (Mean Time Between Failures)
MTBF is total operating time divided by the number of failures. Here is the formula, a worked example, how it differs from MTTF, and a free MTBF calculator.
How to Calculate OEE (Overall Equipment Effectiveness)
OEE measures how much of your planned production time is truly productive. Here is the formula, a worked example, benchmarks, and a free OEE calculator.
How to Measure Your Maintenance Backlog (in Crew-Weeks)
Maintenance backlog is best measured in crew-weeks: estimated labor hours of outstanding work divided by weekly available hours. Formula, healthy range, and a calculator.
Leading vs Lagging Indicators in Operations
Lagging indicators measure outcomes that already happened. Leading indicators measure the activities that predict them. Here is the difference, examples, and how to pair both.
MTTR vs MTBF, Explained: Reliability vs Maintainability
MTBF measures how long equipment runs before it fails. MTTR measures how long it takes to fix. Here is the difference, the formulas, a calculator, and how both drive availability.
OEE vs TEEP: What They Measure and Which One to Track
OEE measures scheduled production time. TEEP measures all calendar time and reveals hidden capacity. Here is the difference, the formulas, and a TEEP calculator.
