Why Measure??To make a decision:–Meet standards & specifications–Detection/reaction oriented–Short-term results–Compare measurement error to specifications?Stimulate continuous improvement:–Where to improve?–How much to improve?–Is improvement cost effective?–Prevention oriented–Long-term strategy–Compare measurement error to product variation
