What Is Mean Time To Repair (MTTR) and Why Is It Important? 

Published: 25 January 2023

In computer systems engineering and management, Mean Time To Repair is a maintenance metric that measures the average time required to troubleshoot and repair failed equipment. This metric provides valuable insight into how effectively an organisation’s IT infrastructure is managed and maintained.

MTTR is one of the four key DevOps Research and Assessment (DORA) metrics.

Let’s take a closer look at what MTTR is, how to calculate it, and why it’s important for your business. 

What Is Mean Time To Repair? 

By measuring the Mean Time To Repair, organisations can evaluate their ability to repair system failures. It provides information about the effectiveness of an organisation’s maintenance processes and helps identify areas where improvement may be necessary. By understanding this metric, organisations can reduce repair times and improve their ability to respond quickly when problems occur.

How To Calculate MTTR  

In order to calculate MTTR, divide the total number of repairs performed during a period of time and the total amount of time spent on those repairs. The formula for calculating MTTR is: MTTR = Total Time Spent on Repairs / Number of Repairs Performed. This will give you the average amount of time needed to complete each repair job. 

Why Is MTTR Important? 

Knowing your organisation’s MTTR can have significant impacts on its overall efficiency and performance. Typically a high value means that there are with your maintenance processes that need improvement to become more efficient and effective. But, if your organisation has a low MTTR, then your maintenance processes are running smoothly and efficiently. This means less downtime and higher overall performance. 

Conclusion 

MTTR is an important metric for organisations looking to optimise their DevOps practices and increase overall efficiency. Knowing your organisation’s MTTR can help identify areas that need improvement and provide valuable insight into how quickly your team can respond to issues. CIOs and VP Engineering should understand this metric in order to measure the effectiveness of their current maintenance strategies—and make adjustments as needed—to ensure maximum uptime at all times!

Developer Analytics

Developer Analytics gives organisations deeper analytics, allowing them to identify opportunities to optimise the performance of their software development teams. This directly impacts the Total Time Spent on Repairs and ensures that time is allocated effectively.
