Chris and Fred discuss what a leader, champion and manager are. Many textbooks, guidebooks and so-called ‘domain experts’ tell us what (for example) a ‘reliability leader’ is. In some cases the ‘reliability leader’ is someone who has little influence, and is more of an ad hoc ‘doer.’ Not a leader. Why is this? Listen to this podcast to hear more about this?

Chris and Fred discuss assumptions – and when you need to check if they are valid. And if you do need to … how do you check these assumptions? Reliability (and all sorts of other engineers) need to study variation and variance. We are often interested in when the first ‘5 percent’ of things will fail. So assumptions on the underlying failure (or random) process are crucial. Sound familiar? Listen to this podcast to learn more.

Chris and Fred discuss how we need to estimate monthly failure rates of a product. Like when bosses or directors want to know what the ‘failure’ or ‘return’ rate of a product is this month. But is this useful? How do we account for the number of products we have shipped? How old are the products when they fail? And how do we learn from these numbers? Can we even find a number? Listen to this podcast to learn more.

Chris and Fred continue the discussion on the history of reliability engineering. The discussion started with Chris and Adam (you can click here to listen to it) and kept going with Chris and Carl (and you can click here to listen to it). Between all of them, they came up with 8 reliability engineering epochs. Now it is Fred’s turn to work out what has been missed, and what all of this means what reliability engineering looks like in the future.

Chris and Carl continue the discussion on the history of reliability engineering. The discussion that started with Chris and Adam (you can click here to listen to it). In the short time they had to talk about it, they came up with 6 reliability engineering epochs. Now Carl is going to see if there is anything to add – and importantly – anything to learn.

Chris and Adam discuss the history of reliability engineering. Everyone (customer, manufacturer, builder) has different ideas of what reliability is. And this has changed throughout history. Perhaps we can learn something from what reliability engineering has also changed throughout history. As they say – those who don’t learn from history are destined to repeat it. This is the first of three podcasts that look at the history of reliability for this purpose: seeing what we can learn to help reliability engineering now and tomorrow.
