QA/QC: Some Things Are Old; Some Are New

摘要

When JPCL's edi- tor invited me to write a nioro about changes in quality assur- ance and quality control (QA/QC) in the industry over the past 30 years, I was honored and motivated. I love our industiv and enjoy writing and leaming as much about it as I am able to. The editor also suggested that the piece not be a "year-by-year account, but something that will be a review to veterans and an easy introduction to newcomers."
