A procedure ensures the validity of each scheme; surveillance activities are planned and reviewed, feeding management review, and the resulting data is recorded for continual improvement. Depending on the scheme, surveillance can include evaluating external products and services, using reference materials or other control items, how participant results are transmitted, control of statistical conditions so that evaluation validity is confirmed, checking of reports and, for continuous schemes, comparison with previous rounds.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
