Design Input & Specs vs. Test & Measure Capability

When defining design inputs and specifications, what does a design engineer need to consider about the test and measure capability? What are the typical ways that we assess the variability that a test or measurement introduces into our result? Transcript Expand You’re listening to an installment of the Quality during Design “Versus Series”. In this…

ALT vs. HALT

Reliability engineers may suggest environmental stress tests. There are many types of tests in an RE’s toolbox. We compare two types of commonly known tests that are used for design: ALT vs. HALT. What are the important distinctions between these two methods? What value do they each bring to design engineering? And how do they…

PRUNE: Quality as a Strategic Asset

Quality as a Strategic Asset vs. Quality as a Control

Viewing Quality as a strategic asset to new product development can help us create those products that others love, for less. We talk about some challenges with new product development, the ideal state, and how we can use quality to get there. Use quality engineering and reliability engineering to P.R.U.N.E. the development process so we…

Design Specs vs. Process Control, Capability, and SPC

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,…

Vs. Banner for Customers

Internal Customers vs. External Customers

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…

Discrete Data vs. Continuous Data

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…
