For details on how probability value and formula are used to determine quality assurance, refer to chapter Quality Assurance in the Concepts section for Stardust.

Quality Assurance Performer

Probability

The probability determines the percentage for quality assurance performed on activities. The default probability has to be an Integer value between 0 and 100. For example:

• 100%: results in performing quality assurance on all activity instances, only depending on the formula result.
• 75%: result in performing quality assurance on three out of four of all activity instances in average (if formula results in true).
• 50%: result in performing quality assurance on half of all activity instances in average (if formula results in true).
• 0%: result in no quality assurance regardless of the formula result.

The default value is 100%. If the value is outside the accepted range, an error message appears.

Formula

The Formula section provides a JavaScript editor, where you can enter a formula that will be evaluated during runtime to check if this activity needs quality assurance. The default value is true. For details on how this formula is evaluated, refer to section JavaScript Expression of chapter Quality Assurance in the Concepts section for Stardust.
