IDENTIFY RESPONSES TO BE MEASURED

IDENTIFY FACTORS TO BE STUDIED & ITS LEVELS TO INDUCE A MEASURABLE SIGNIFICANT CHANGE TO THE RESPONSE

DEFINE OBJECTIVE & PROPOSE HYPOTHESIS

DETERMINE NO. OF EXPERIMENTAL RUNS TO PROVIDE ENOUGH POWER (80%) FOR PRECISION

OF TEST MODEL WITH CONFIDENCE INTERVAL (95%) FOR ACCURACY

INSIGNIFICANT

1D INTERACTION PLOT

2D CONTOUR PLOT

ANALYSIS OF VARIANCE (ANOVA) FOR PREDICTION EQUATION IN TERMS OF ACTUAL & CODED EFFECTS

BLOCKING

GRAPHICAL OPTIMIZATION WITH OVERLAY PLOTS (DESIGN SPACE) FOR FINDING OUT OPTIMIZED RANGES OF CRITICAL FACTORS BY SETTING ULTIMATE GOALS FOR MULTIPLE RESPONSES TO FIND REGIONS WHERE ALL THE REQUIREMENTS SIMULTANEOUSLY MEET FOR ALL THE CRITICAL FACTORS KNOWN AS A "SWEET SPOT".
