HALT (Highly Accelerated Life Test) uses the weakest link mentality. We apply stresses beyond what our designs would normally see in the environment to make something fail. It’s meant to be an iterative test program where you are testing, analyzing the results, determining the root cause, fixing the design, and then testing it, again.

This blog reveals more about its roots, why you should perform HALT (or not), when in the design process it’s best (hint: really early), and who likely needs to be involved. Also understand how HALT is different from ALT.

Quality folks use and promote some standard problem solving and continuous improvement methods, and you’ll want to reference the right acronym when getting buy-in for your improvement project. You may have heard of PDCA, PDSA, and DMAIC. You vaguely know they’re improvement, but don’t really know what their differences are. When should you use which one, and for what? This installment demystifies the titles and explores the history of each so you can talk about the right tool for your project.
