Quality during Design

This fourth episode of the "QDD Versus" series focuses on concepts relating to Design for Manufacturability. Understand how design specs fit into process control, process capability, and SPC and where they typically don't fit at all.

We talk about things to think about when setting limits on design features.
And, when defining controls for potential failures, knowing how processes are controlled can help us decide if the controls we have are good enough or not.

 We talk about customers of design information. It takes many people to realize a product design into something that can be sold and used. Those people need design information to ensure that they're performing their tasks to produce a high-quality product, and to be able to use our product appropriately. We review who our customers are and what type of information they need from design engineers.

Once we've decided to control something (think of our prevention and detection controls), we then need to decide how to measure it. Different controls may need different measuring requirements, which can give us discrete or continuous data. We treat these data types differently when collecting it, determining sample sizes, and analyzing it for results. Tune-in to learn more about how to take the next step in defining controls: figuring out how to measure it and considering the data.

Not all controls are equal, and we don't have to wait for something bad to happen to start designing with them. We compare different types of controls in product development and design engineering: Prevention Controls vs. Detection Controls. We review concepts, uses for controls, risk-based controls, and how to prioritize design efforts for the right controls.

Your team is faced with a complex decision. Maybe it's complex because you have a lot of options or maybe it's complex because it's technically challenging and requires some testing. You may want to consider a structured approach: DMRCS.

Define
Measure
Reduce
Combine

 We’ve identified safety concerns about our product design. How concerned do we need to be about quality while we’re determining root causes? There is an intersection of quality, reliability, and safety. We talk about how they fit together.

We’re at the concept phases of our product design, trying to get our heads around the high-level steps that our users are going to take to use our product. We have an idea that we’ll have many different user groups interacting with our product, but we’re not so clear about the big picture – who is doing what, when and who needs what afterwards. To put it all together, we can help ourselves with a common quality tool: a SIPOC diagram.

SIPOC is an acronym for Suppliers, Inputs, Process, Outputs, Customers

We talk about when to use it and what steps to take to complete one (hint: we don't usually fill it in from left-to-right).

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? We step through an example of a situation where we're thinking about our product design in this way.

There is a rather large family of test methods associated with Qualitative Accelerated Tests. They're also known as RETs (or Reliability Enhancement Tests). 

Today, we’re focused on the models that are used to help us with the design. Awareness about these methods will help us with future test plans and project management. We talk about environmental stress testing and remind ourselves a little about HALT.

We’re developing requirements for our product, including setting reliability requirements. 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, using our FMEA (failure mode effects analysis). 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.
