Choosing a Confidence Level for Test using FMEA

We should choose a confidence level for our requirements or their test plans. We can associate that confidence level with the level of risk associated with our product. FMEA is a great tool for us to refer to, to help us choose a relevant confidence level by basing our decision on one or more metrics that the FMEA can provide.

Getting Started with FMEA – It All Begins with a Plan

We’re starting to populate an FMEA table with our team. We get it started, but then we get stuck in disagreements. Or we think we finish it and then we don’t know what to do with it.

We can avoid these headaches with a little planning (or maybe a lot of planning – it depends on the project). We talk about risk management planning, as it relates to FMEA.

How many controls do we need to reduce risk?

When we’ve identified a risk to our design or user process – and that risk can pose a potential harm – how many controls do we need to add? We discuss prevention vs. detection controls, ALARP, as low as possible, and some scenarios where we could (and maybe couldn’t) justify a risk as acceptable without…

Designing Specs for QA

Creating specs for suppliers and producers is generally at the forefront of our thoughts about the activity. But, it’s also important to design for our QA friends, too, for inspection. We talk about what acceptance sampling is all about. We also step through a thought process for identifying and creating design features for inspection using…

Every Failure is a Gift

When designs fail we can take on damaging mindsets while we’re deciding our next steps, and this can lead us to bad decisions. We explore this and give some examples of pitfalls. We also talk about what to do within the design-realm to prepare for and combat those mindsets. Finally, I share my mantra when…
