Before we get into the explanation of MTBF, MTTR and MTTF. It's important to know that asset performance metrics are critical for any organization whose operations depend on equipment. Only by tracking what is likely to fail can an organization maximize availability and minimize downtime.<\/p>

Asset performance metrics are critical for any organization whose operations depend on equipment. Only by tracking what is likely to fail can an organization maximize availability and minimize downtime.<\/p>

Tracking asset reliability is a challenge that engineering and maintenance managers face on a daily basis. While failure metrics can be very useful in this context, to use them effectively, you need to know what their acronyms mean, how to distinguish them, how to calculate them, and what it tells you about your assets.<\/p>

Even the most efficient maintenance teams experience equipment breakdowns. That's why it's essential to plan for them.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

But first, what does equipment failure look like?\n\n<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Failure exists in varying degrees (e.g., partial or total failure), but in the most basic terms; a failure simply means that a system; component or device can no longer produce the specific results desired. Even if a piece of manufacturing equipment is still running and producing items; it has failed if it does not deliver the expected quantities.<\/p>

Proper management of failure can help you significantly reduce its negative impact. To help you effectively manage failure; there are a number of critical metrics that should be monitored. Understanding these metrics will eliminate guesswork and give maintenance managers the hard data they need to make informed decisions.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Across all industries and applications, we've found that these are MTTR, MTBF and MTTF. We will discuss what each of these acronyms mean and how you can use them to improve your operations.<\/p><\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

But before we do, we need to discuss something that is often overlooked: the importance of having reliable data behind your failure indicators.<\/p>

In order to make data-driven improvements in the event of equipment failure, it is crucial that the right data is collected and that the data is accurate.<\/p>

High-level failure statistics require a significant amount of meaningful data. As we will show in the maintenance indicator calculations below; the following inputs should be collected as part of your maintenance history:<\/p>
