Book excerpt: This study guide is helpful for anyone planning to take the ASQ Certified Quality Engineer (CQE) exam. The book has been developed specifically to address the 2022 CQE Body of Knowledge (BoK). Every practice question includes an explanation of the correct answer along with the corresponding section of the BoK for further study, and over half of the 600+ questions have been revised and improved. New topics include data automation and database integration, cost-benefit analysis, the RACI matrix, assessing risks in auditing, overall equipment effectiveness, critical-to-quality concepts, 5 Whys, and a much more intensive treatment of risk management.
