SOR 458 Testing in the Flat Part of the Curve
Testing in the Flat Part of the Bathtub Curve
Abstract
Chris and Fred discuss the question posed to us by one of our listeners regarding the ‘flat’ bottom of the ‘bathtub curve.’ Just a bit of background – the ‘bathtub curve’ represents the hazard rate of a system. That is, it helps us understand the probability that a product that works ‘now’ will fail. The ‘flat’ part of the curve is often cited as the ‘random’ part of the curve where failure is caused by environmental overstress conditions. So how do we test for this part of the curve? … but hang on – is the ‘bathtub curve’ even a thing? Is it even relevant for the useful life of a product? If this intrigues you, listen to this podcast!

SOR 457 Is Maintainability Only About Repair Time?
Is Maintainability Only About Repair Time?
Abstract
Chris and Fred discuss one of the most popular interpretations of maintainability which is based on how long it takes to maintain something. We see so many textbooks and guides that focus on this metric as the only maintainability measure. But is this really all that matters? What about the number of technicians required? … the number of tools required? … the training required for these technicians? … the mass of these tools? Does reliability matter? Yes to all these things. But how does they relate to the time-based definition? They don’t. Listen to this podcast to learn more.

SOR 454 What if You Make it Too Reliable?
What if You Make it Too Reliable?
Abstract
Chris and Fred often hear at least one person (or a small group of people) challenge your ‘cultural’ reliability improvement initiative. We hear things like ‘but to make it very reliable, it becomes too heavy or expensive.’ We also hear things like ‘but to make it very reliable, we need to invest lots of money for something the customer won’t buy.’ If you boil their complaints down or get to the hub of their issue … they are really suggesting that we do ‘reliability things’ without thinking. A checklist of activities that may or may not be valuable. This could not be further from what actually happens in reality. It never happens. Listen to this podcast to learn more.

SOR 453 How to Balance Reliability vs New Tech
How to Balance Reliability vs New Tech
Abstract
Chris and Fred discuss how we balance … or incorporate new technology with reliability. Is reliability something that only comes with legacy or age? … as in old technology? Can you make a product that is based on new technology and have it reliable? … are these concepts mutually exclusive? If we look at this from an ‘asset management’ perspective, there is a movement out there that we need things like increasingly sophisticated sensing technology to ensure reliability, availability, throughput or whatever it is we are trying to improve. From a ‘developmental product’ perspective, does new technology mean ‘all bets are off’ when it comes to reliability? Well … we talk about these things in this podcast. ᐅ Play Episode

SOR 450 Customer Experience and Failures – Its not you its them!
Customer Experience and Failures – Its not you its them!
Abstract
Chris and Fred discuss what it means to ‘fail.’ Not from a personal sense! But what does it mean for your product to fail. Engineering or design specifications describe what the product or system must do. So does failure simply occur when the product can no longer meet all these specifications? What if your product or system meets all these criteria – but your customer ‘thinks’ is has failed? We have seen many instances where a group of people who design and make products will vehemently argue that even if the customer thinks something has failed when it meets the specifications, then nothing is wrong. Is it? What do you think the customer will do? Do you think they will be ‘happy’? If this is a problem you come across, then listen to this podcast.

SOR 449 When to Use a Previous Test Plan
When to Use a Previous Test Plan
Abstract
Chris and Fred discuss when (and if) you can use a reliability test plan that you have used before. If it worked then … why won’t it work now? Won’t you save money, time and other things that you can get bonuses for? Well yes. We received a question from one of our listeners who asked why you might not want to test the product the same way. There are many good reasons why you wouldn’t want to do this. If you want to learn more, listen to this podcast.

SOR 446 Battery Reliability Considerations
Battery Reliability Considerations
Abstract
Chris and Fred discuss battery reliability issues and how batteries fail. This based on feedback from one of our listeners (thanks!) There is a lot of energy in batteries that if failure allows this energy to be able to ‘do something’ … then catastrophic failure is an understatement. But as with everything, it is all about the customer. Is failure (for example) when battery capacity reaches 80 per cent of its original value? Is this 80 per cent figure going to be the advertised capacity? If you would like to learn more, listen to this podcast.
