Aliasing occurs when the estimate of a factor effect  is difficult to distinguish because of the impact of other factors in your experiment. […]

The Alternate Hypothesis, written as Ha, is a subset of the larger topic of hypothesis testing. The Alternate Hypothesis is the default statement about a specific condition of your data and allows you to draw important conclusions about the population from which the sample data came.

The bad news is that you have problems to solve. The good news is that there are a number of simple, yet powerful tools that can help you. The 8D process is one of them.

At the gun range, your goal is to hit the target. Accuracy will be measured by how close you come to that target. The same is true of your process.  

Don’t you hate it when you make a mistake? Well, an alpha risk is just that. Let’s learn what that mistake is and how to keep from making it.
