MTTR
MTTR stands for Mean Time To Repair, which is a basic measurement used in maintenance and repair work. It tells us how long it typically takes to fix something when it breaks down. Think of it like measuring the average time a mechanic needs to repair a broken machine and get it running again. Companies use MTTR to understand how efficient their maintenance team is and to plan their maintenance schedules. A lower MTTR is better because it means equipment gets fixed faster, which saves money and keeps production running smoothly.
Examples in Resumes
