Process Maturity Ranking

• R6 - most mature process with regular calibrations recorded on SPC charts.
• …
• R1 - least mature - only run once ever.

The Key/Legend for this table's A...R6 values is at the bottom of the page.

Process Ranking Table

Processes in the table above are ranked by their "Process Maturity Level" as follows:

Process Level	Description of Process Level Ranking
A	Process Allowed and materials available but never done
R1	Process has been run at least once
R2	Process has been run and/or procedure is documented or/and data available
R3	Process has been run, procedure is documented, and data is available
R4	Process has a documented procedure with regular (≥4x per year) data or lookahead/in-situ control available
R5	Process has a documented procedure with regular (≥4x per year) data and lookahead/in-situ control available
R6	Process has a documented procedure, regular ( ≥4x per year) data, and control charts & limits available
