Assessing Risks

You can assess and mitigate risks by evaluating Action Priority (AP) or Risk Priority Number (RPN). To evaluate an AP or RPN, you need to assign the occurrence ranking to each cause, and assign the detection rankings to each control.

Before you begin:
  • Select a severity.
  • Select a cause in the corresponding cell of a causality relationship. For more information, see Editing Causes.
  1. To assess occurrence and detection, click the corresponding cell and select a value from the list.

    Note: A pattern matching and case-sensitive search is available to narrow down the list.

    The selected value is displayed in the cell and can be edited.
  2. Optional: To define another value, double-click the cell and enter text.

Once the severity, occurrence, and detection have been selected, and depending on the template applied on your table:

  • The AP is produced and the AP cell is completed.
  • The RPN is computed and the RPN cell is completed.

You can now search for the actions to reduce the risks of your system.
