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?
To help plan future tests and projects, we review qualitative accelerated test models that can be used early in a design process.
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.
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 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.
