Machine downtime is one of the biggest cost drivers in production.

Every unplanned downtime brings processes to a standstill and causes delays that directly impact productivity. This is exactly where the MTTR (Mean Time to Repair) metric comes in: it shows how much time passes on average before a defective machine or system is ready for use again. 📊

But MTTR is more than just a number on paper; it reflects the efficiency of maintenance processes. Consistently measuring, analyzing, and optimizing this value creates the basis for more reliable production, better resource utilization, and lower costs in the long term. 📉

In this article, you will learn:
✅ How MTTR is defined and correctly calculated
✅ Practical examples that illustrate why this key figure is so important
✅ Strategies you can use to reduce your repair times in the long term
