Quality control labels help you track inventory and determine if specifications were met for raw materials, finished goods and equipment. Healthcare services, manufacturers, distribution companies and more use quality control labels in their operation. Quality control labels document dated inventory, medications, equipment, instruments, charts and more. They help identify products that are tested and approved, or rejected, to ensure only the items that meet standards are used or shipped out. Examples of QC include technical reviews, software testing and code inspections. Testing is a subset of QC. It is the process of executing a system in order to detect bugs in the product so that they get fixed.
