Similarly to other descriptive methods, subjects are screened based on their performance on discrimination tests and verbalization in the QDA® methodology. Standards for subject qualification are arbitrary and may vary depending on the project. A panel of ten to twelve is recommended in QDA® 3. During training, test products are served as illustrative stimuli for the consensus language development. The panel leader works as a communication facilitator without involvement and interference with panel discussions. References can be used for generating sensory terminologies, especially when panelists are confused and disagree with each other on some sensory attributes during training sessions3.
