Process Control Data are standardized process, run by staff, allowing for day-to-day or year-by-year comparisons of a tool's performance. This is similar (but not identical to) Statistical Process Control.

These are the same links found on individual tool pages, in the Recipes > <<tool page>> > Process Control section.
