# Genesys Quality Management Suite 8.1.520 : Selection of Random Calls

Selecting the minimum number of calls required for evaluation at random removes the element of bias in the evaluation process.The Random selection can be targeted by setting the appropriate parameters in the basic and sub criteria fields.

The Allow random calls selection option is enabled by default in the Evaluation Planner, but this setting cannot be changed unless evaluation sub-criteria have been defined. When using the Get Random Interactions function while performing an evaluation, Quality Manager only selects interactions that have not yet been used for evaluation. Add specific interaction is not available when planning group evaluations.

## Selection logic for adding random interactions

When is planned evaluation with main criteria and sub-criteria following logic is applied when user clicks Add Random Calls button.

- Call Selection Rules as their are defined for the questionnaire have absolute precedence. For example if user selects in Call Selection Rules for questionnaire only calls from Monday and Tuesday, then no calls from other days will be added to the evaluation even if main criteria or sub-criteria contains other days than Monday and Tuesday.
- Sub-criteria are processed from first sub-criteria to the last sub-criteria one by one in sequential order
- If Allow random calls selection is enabled and not enough calls were found by sub-criteria then selection of random calls continues with Basic criteria
- If Allow random calls selection is disabled and not enough calls were found by sub-criteria then selection of random calls does not continue and evaluation will contain not enough calls - in that case user can manually add specific call(s) to fulfill minimum count of the interactions configured for Basic criteria
