Professional Certification: A Study of Significance

摘要

Two hundred and thirty five American Society for Quality and Society of Manufacturing Engineers professionals participated in an internet survey to determine if professional certification by an individual makes a financial difference in Quality Cost Improvement or Waste-Cost Reductions. After a two-round posting of the survey, independent t-test statistical results indicate that neither Quality Cost Improvement nor Waste-Cost Reductions experienced significant differences between small, mid-sized, or large manufacturing companies with or without certified employees.
