Risk Barriers as Swiss Cheese?
There’s a model that can help us visualize and consider the different barriers to harm: The Swiss Cheese Model of Accident Causation. Learn what makes up this model and how ideas are represented. There are also different ways that the model is being used today. How can we design for controls, policies, or actions that are part of the use of our product but outside of our control?

I’ve got a riddle for you today. What does swiss cheese and risk management have in common? I’ll tell you the answer after the introduction. Hello, and welcome to Quality during Design, the place to use quality thinking to create products others love, for less. My name is Dianna. I’m a senior level quality professional…

Environmental Stress Testing for Robust Designs
To help plan future tests and projects, we review qualitative accelerated test models that can be used early in a design process.
Read MoreEnvironmental Stress Testing for Robust Designs [transcript]
We’re starting out with a new product design. We’re really not sure if the components we’re choosing are robust enough for the field conditions we’re expecting our product to function within. There’s a set of tests that can help with that. Listen in for more about environmental stress testing. Hello and welcome to Quality during…

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.
Read MoreChoosing a Confidence Level for Test using FMEA [transcript]
We are developing requirements for our product, including setting reliability requirements and its confidence levels or we’re setting acceptance criteria for our test plans. What confidence levels do we choose? We don’t have to blindly set them. We can base it off the risks of failure. I’ll tell you how after this brief intro. Hello…
Read MoreGetting 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.

We’re jumping into an FMEA starting to populate table cells and organize information. We may even be doing things right, having a team approach and inviting our cross-functional team members to the discussions. We get started, but then we don’t agree on ratings to assign, like severity, occurrence, or detection ratings. Or we get anywhere…
Read MoreHow can 8D help solve my recurring problem?
We talk about the 8D methodology, describe situations where we could benefit from it, list each of the 8 Disciplines, and compare it to PDSA and DMAIC.

What is 8D? Now, we’re not talking about 8 dimensions and things like quantum physics. We are talking about a quality tool, a system and a methodology for fixing a problem. So, what is it? How does it compare to some of the other common continuous improvement and problem-solving methods? And when we want to…
