What You Need to Know About MTBF
An Accendo Reliability recorded webinar event
MTBF stands for ‘mean time between failure.’ This sounds intuitively easy to understand. But … if you haven’t taken the time to understand MTBF, and your organization relies on the reliability of its products, you are almost certainly in trouble.

RRP 061 Why You Shouldn’t Rely on MTBF with Fred Schenkelberg
This week, I welcome Fred Schenkelberg back to the show to talk about mean time between failures and the basics of reliability math. Long story short, I hope you’re not using MTBF as a proxy for reliability!

SOR 422 What Do I Do When the MTBF is Imposed on Me?
What Do I Do When MTBF is Imposed?
Abstract
Chris and Fred discuss what happens when you can’t avoid having the MTBF imposed upon you – even if it is your own organization and not the customer. Perhaps you are told that ‘our competitors quote the MTBF … so we have to as well!’ But you can (sneakily) tailor test data to get whatever MTBF you want. You can make life easy on yourself by not challenging this paradigm (noting that you will most likely get an unhappy customer). But it is almost impossible to apportion MTBF goals to individual designers that even allow the motivated ones to create a reliable system. So what do you do? Listen to this podcast to help you on your reliability journey.

A Series of Unfortunate MTBF Assumptions
A Series of Unfortunate MTBF Assumptions
The calculation of MTBF results in a larger number if we make a series of MTBF assumptions. We just need more time in the operating hours and fewer failures in the count of failures.
While we really want to understand the reliability performance of field units, we often make a series of small assumptions that impact the accuracy of MTBF estimates.
Here are just a few of these MTBF assumptions that I’ve seen and in some cases nearly all of them with one team. Reliability data has useful information is we gather and treat it well. [Read more…]

Why can’t we shake off MTBF?
Mean Time Between Failure (MTBF) is one of the most well know reliability metrics. 
But to anyone who works with reliability, it seems like it was developed by some evil anti-reliability mastermind to undermine the possibility of connecting reliability to anything or anyone.
Mean Time Between Failure means what?
- It’s the time between two failures? –
- It’s when the first failure occurs? –
- It’s how long the product is good for?
- It seems way to big to be a reasonable goal! “How can an air pump have an MTBF of 4 million hours? That’s ridiculous these things are only supposed to last for five years!
This is the process of understanding everyone goes through as they are introduced to MTBF, formally or informally. [Read more…]

You have carefully crafted a detailed reliability goal including function, environment, probability, and duration, plus apportioned it to critical supplied subsystems and components. Your vendor decides to use MTBF instead.

04 – What is MTBF and Why You Shouldn’t Use It
What is MTBF and Why You Shouldn’t Use It
Mean Time Between Failure or MTBF is almost universally recognized in maintenance, reliability, and asset management.
Why is that? And does it actually help an organization improve the reliability of their assets?
The answer is a resounding No.
