Calculated Risk Score

Risk lookup table is to get the risk value corresponding to the success probability value and impact value.

sn_chg_probability_risk_lookup table is used to fetch the data to calculate the risk value of the change request.

Defining probability ranges

By default, there are nine records with all the possible mappings for Impact and Success Probability along with their corresponding risk values.

Managing risk lookup records

You can add and delete records in the table. The Check impact and probability combination business rule validates duplicate mapping entries.

Navigate to All > Change > Administration > Calculated Risk Score.

All risk calculating engines calculate their corresponding risk value. The system picks the highest risk and defines the risk for the change. You can modify the risk values irrespective of the values defined for Impact and success probability.

You can view the success probability definition that set the success probability on the change request by accessing the sn_chg_probability_details table. Users with read access to change requests can access this table.

On the change request form, in the Related Links section, select Calculate risk. The risk engines calculate the risk for the change. Select the icon next to the Risk field to view the risk set for the change.

Select the icon next to Calculated Risk Score to find which type of success probability definition sets the risk for the change. There are three types of calculated risk score:

• Calculated (Impact + Success Probability)
• Calculated (Impact + Change Success Score)
• Calculated (Impact + Change Model Success)
• Not set: When the risk is not evaluated

Note:

Risk lookup supports domain separation. The sn_chg_probability_risk_lookup table is process separated when you install the domain separation plugin.
