· WHAT? combinations of individual parameters for process control are varied, and their effect on the output quality are measured. From this we determine the sensitivity of the process to each parameter.
· WHY? Because randomly varying individual parameters takes too long.
· e.g. A One-Factor-At-A-Time-Experiment
· The example shows how the number of samples grows quickly.
· A better approach is designed experiments
· e.g. DESIGNED EXPERIMENT for springs in last section
