Determine Design Goals
Kelly Avery, Rachel Haga

The specific choice of design should be tied to the test objectives and the anticipated analysis. For example, designs meant for factor screening have fundamentally different properties than designs meant to characterize or optimize. This lesson discusses three common test objectives in detail and describes how experimental designs can be applied to ensure these objectives are met. Sequential test design strategies, where the results of early tests inform the construction of future tests, are highly recommended and can provide additional resource savings.
