Control charts really should be an integral Element of any high-quality management or 6 Sigma initiative. They offer a data-pushed approach to make knowledgeable conclusions, track system security after a while, and reduce defects by eradicating assignable brings about of variation.
Since technology just isn't heading anyplace and does more excellent than harm, adapting is the best system of action. That is certainly where by The Tech Edvocate comes in.
