Design of Experiments classes always talk about Resolution III and higher designs. But what is a Resolution II design? We show what it is – and show that it is actually used quite a bit! Should be used with caution as it does not provide understanding.

Design of Experiments (DOE) is often only taught as a series of tools. Instead, we have used it as a tool in the Decision-Making Process which enhances implementation.
Each section below contains a 2-minute video to expand on the topic provided.
The setup and project definition are important for future success. Often, people want to jump to a solution. Then, they can start implementation and testing. Briefly pulling back to define the goal and appropriate outputs will help tremendously.
Historically, it has been relatively easy to meet customer system requirements using basic testing techniques. Today, however, customers require faster changes in technology and requirements are getting more difficult to meet. Competitive cost pressures have made the achievement of goals an even tougher task. In some cases, customers have requested and in a few cases mandated tools for companies to “be more efficient and organized in testing”. These facts create the need for organized and effective testing methods to be incorporated in all phases of the development process. [Read more…]
Perry defines Design of Experiments with one simple statement.
“A tool to assist in the process of understanding a system.”
Just 2 minutes and 10 second long, lets break down and understand each phrase in this basic definition of design of experiments. [Read more…]
During the design phase, we make decisions that create the eventual reliability performance of a product.
It is the decisions we make that matter.
Also during the design phase, we explore numerous questions. [Read more…]
