The objectives for conducting a designed experiment are the following:

  • Find the most important factors/variables affecting a response(s).
  • Determine the best settings to improve the response(s) for the important factors.
  • Determine the cost effective settings for the factors that are not important.
  • Provide the required information in a timely, efficient and cost effective manner.
