For example: In the following rule outcome table for rule 003:

Sub-rule ref	Outcome	Typology Score Value
003.00	Payee account dormancy = FALSE	0
003.01	Payee account dormancy 3 = TRUE	33
003.02	Payee account dormancy 6 = TRUE	67
003.03	Payee account dormancy 12 = TRUE	100
003.04	Payee account dormancy = FALSE	0

In other words, if there had been no transfer requests from or to the account in 211 days (i.e. 003.02 = TRUE), the contribution of this rule (003) to the typology score would be 67 (can we call them rule points?)

...

It makes sense for the typology processor to be able to interdict a transaction directly, if the threshold for interdiction has been met. This trigger was initially intended to be processed by the CADProc and may still be added to the CADProc for interdiction triggers over an aggregated assessment over a number of typologies, but it is more efficient to let a typology trigger its own interdiction immediately on a threshold breach.

For a given typology, a specific threshold value must be linked to the typology for the following workflow outcomes:
1. Interdiction: If a typology score is equal to or greater than this value, the Typology Processor will trigger an interdiction workflow to instruct the client system to block the transaction.
2. Review: If a typology score is equal to or greater than this value, the Typology Processor will trigger an alert to the Case Management System to initiate an investigation into the transaction.
3. None: If a typology score is less than the Review threshold, no triggered action is taken by the Typology Processor.
The threshold for interdiction and investigation will be defined in the typology configuration.
