As the specifications get more explicit, the tolerances get lower and the client becomes more proficient in the latest image-measurement techniques, we need to rethink what, why and how we define and quantify our products and processes. For example, why we should measure biaxial stress of the mesh? How do we adapt static tension as a predictor of consistent dynamic tension? How do we know when the EOM and RzS2 are too high, or whether or not to give up durometer in favor of fit, flexion, fade and fatigue? This presentation is jam packed with common sense — but not common knowledge — that you can take back to the shop and implement immediately for little to no cost.
