ABC FredLittle Compromises and Future Costs

In a recent Seth Godin blog, Counting beans he talks about the eventual costs of little compromises. The immediate benefit may be celebration worthy, yet

But overlooked are the unknown costs over time, the erosion in brand, the loss in quality, the subtraction from something that took years to add up.

This certainly applies to reliability as well. Deferring maintenance just one more month, addressing one more software bug can be done after shipping, and similar small shifts erode reliability of your system. Continue reading →

ABC FredIn a customer’s mind, the product works or it doesn’t. If it doesn’t work as expected it has failed. This may or may not be a reliability problem.

A customer or someone using your product brings a set of expectations to the experience. The range of expectations may range from very little to very high functional, value production, and durability.

Failures are defined by customers. Continue reading →

ABC FredUse / Environmental profiles

Did you know that hot air doesn’t rise when there is no or very little gravity?

The electronics used to steer an oil exploration drill head 5 miles deep in the earth experiences 200°C sulfuric acid immersion along with continuous 50,000G shocks.

I used to think the environment under the hood a car was difficult. Continue reading →

ABC FredThe term variance is a statistical concept related to the spread or dispersion of a set of data. Second to the mean, it a common value we may calculate.

We find standard deviation easier to understand and use (it uses the same units as the data) whereas variance uses the units squared.

We use variance in quite a few different ways. Let’s review just a few. Continue reading →

Chapter 7 Design for Reliability of the book Practical Reliability Engineering starts with:

The reliability of a product is strongly influenced by decisions made during the design process.

ABC FredThe key message here is reliability occurs at the point of decision. Each time someone makes a decision, selects a component, chooses a material, assumes a use profile, the eventual product reliability takes shape. Continue reading →
