What is Risk Rating Score

The Risk rating based graphs on the dashboard allow capturing a different picture of the study's current status. Instead of simply accumulating the binary information about whether the threshold of certain risk indicators was breached, a special preprocessing step was introduced. This step allows investigating the current status of sites for systematic behavior in the breaches of risk indicators.

A score for occurrence and severity is introduced.

The occurrence describes how often and how long thresholds were breached and takes into consideration past breaches as well. This way the scores reflects systemic issues of a risk indicator and of individual sites.

The severity score reflects the systemic of an indicator across all sites. This allows capturing information about how widespread the indicated risk can be.

E.g., a high occurrence score of a risk indicator suggests that the thresholds are breached by many sites and that the breaches are of systematic nature. A low severity score indicates that the coverage of it is declining and not many sites are affected anymore.

To capture this relationship a third score is shown: the risk rating score. A high score suggests a systemic risk across many sites. Sites can be ranked by this score and the rank reflects urgency.

This score can be viewed by choosing a concrete risk indicator in the risk rating overview graph and looking at the site to site comparison graph.

If a risk is selected instead, the graphs represent the mean occurrence and severity over each affected site and indicator.

If nothing is selected in the Frisk rating overview graph, a mean overall risk is displayed.
