What else can we call maintenance if not maintenance? I recently wanted to set up a maintenance group and name it "Maintenance Group" but the leader insisted that it was inappropriate.

QC Department = Quality Inspection Department. Quality inspection work is divided into incoming goods inspection (IQC), quality testing (QA), process inspection (IPQC), final inspection (FQC), etc. The quality inspection work includes Some repair work. In actual work, if maintenance work is secondary to quality inspection work, it can be collectively referred to as quality inspection.
