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
