I have been working with clients recently who are keen users of FMEA. Getting engineers to contribute potential failures and their causes is not a problem with these clients, but ensuring that actions are correctly identified and followed up is not so easy. So, what goes wrong? What differentiates a good FMEA from a great FMEA? [Read more…]
Achieving the Benefits of Reliability
Reliability engineering, analysis, management, testing… − Where do I get the skills and training to be really effective? University or College? In-house? Conferences? Webinars? Software or Equipment Suppliers? Journals? A colleague? − Do I need a Certification? − Do I need an integrated program, or only specific stand-alone techniques?
Everyone has to start somewhere. And if we are going to be smart about it, we should examine our needs and make a plan… [Read more…]
Plan Your Reliability Testing with Intent
I wonder how many product tests have been undertaken and nothing has been done with the results? Maybe development activities have moved on before any results are available? Maybe the test results didn’t provide the answers that were needed? Maybe the test wasn’t focused on the critical issues. In other words, cost, time and resources were wasted.
I will present a better way to ensure value is delivered and test results are acted upon. [Read more…]
We have “reliability” in our job title? Therefore, we must promote reliability across all our company products as our first priority?
If you believe that, then I believe you are a slave to reliability.
A project manager or design engineer comes to us and makes a proposal that would adversely impact product reliability. We’d reject it, yes?
Well, I believe, on both counts, we should first take a step back and review the alternatives. [Read more…]
Ensuring Reliability Data Analysis Leads to Positive Action
Convince, don’t confuse! Justify, don’t exaggerate!
Project managers want to deliver their product on time and on schedule. Design engineers want to believe that they have got it right. But your analysis, test results and field data suggest that there might be a problem. What do you do?
The key words here are “suggest” and “might be”. How should you present your evidence and analysis such that it doesn’t exaggerate with certainty, or confuse with statistics? How should you ensure that your conclusions lead to positive action? [Read more…]
We need insight when defining requirements
We all probably know Fred’s fight against the use of “MTBF” as a default measure of reliability.
And I concur. “MTBF” offers the least insight to product reliability. It offers little to the user in terms of realizing the benefits of reliability.
However, we all would like to see products that deliver more appealing benefits; and reliability is a key factor. But reliability is only part of the equation.
Technical performance is important.
So is price. So is appearance. So is delivery. So is the customer: different customers may see the world differently. And so may your competitors.
So, we can’t all adopt the same measurement for reliability. [Read more…]
