What is Quality? Ask people involved with the design and manufacture of a product the following question: “What is Quality?” Many if not most of the responses will be some form of the following: “Quality is ensuring that our products meet the customer (or engineering)...

In the last Blog, we explored the use of contour plots and other tools (such as a response optimizer) to help us quickly find solutions to our models. In this blog, we will look at the uncertainty in these predictions. We will also discuss model validation to ensure...

In the last Blog, we learned how to work with predictive models to find solutions that solve for desired responses. We used some basic algebra to solve for solutions and looked at the use of contour plots to quickly visualize many solutions at a glance. In this...

In the last Blog, we learned how to determine the coefficients of a predictive model for 2-level screening designs.It is more complex to determine model coefficients for multi-level experiments so for those, we rely on statistical methods software. In this blog, we...
