Design of Experiments
Statistical method for deliberately varying multiple factors to quantify their effects and interactions on outputs.
Examples
- 01A Green Belt uses a DOE with 3 factors, temperature, pressure and time, to find the best setting for a plastic weld.
- 02During Analyze, the DOE reveals that temperature and pressure interact, something one-factor tests would miss.
- 03The optimal DOE settings are written into the control plan and checked after the first month of production.
