Design of Experiments 
Introduction
Experiments are frequently conducted to improve/optimize existing processes or to evaluate new and emerging technologies. If properly designed and executed, such experiments can provide huge returns on investment and increase competitiveness. Unfortunately, many experiments suffer from poor planning, design, and execution. For example, the test data may not have been obtained in a manner that provides the desired information, or once obtained, subsequent summarization, display, and analyses may fail to fully properly reveal the information contained in the data.
Successful Experiments

Successful experiments are characterized by five components:

  • Planning the experiment
  • Designing the experiment
  • Displaying test results
  • Analyzing and interpreting test results
  • Documenting the experiment and test results

These five components form the basis for this short course. Methods are presented for:

  • Planning and designing experiments
  • Techniques are demonstrated for effective displays of test results
  • Robust procedures are presented for analyzing and interpreting test results
  • Emphasis is placed on the need for documentation throughout the experiment.

Actual data from ongoing reliability test programs used to evaluate new processes and materials for the production of circuit cards used in military hardware are used for illustration.
