Design of experiments are crucial in planning, conducting, analyzing and interpreting controlled experiments to determine which factors are the most effective in controlling the value of a parameter(s).

By planning and strategically implementing experiments, researchers could gather  really useful information of the effect(s) on a response variable due to one or more factors.

The main concepts in designing a DOE include blocking, randomization and replication.

In order to begin a DOE, researcher should identify:

  • Key factors
  • Settings that could affect performance
  • Are there any interactions expected
  • How to minimize variation in output

Design options:

  • Screening designs
  • A response surface design
  • Mixture Designs
