Profiling Dynamic Design Section

Introduction

Quantitative descriptive testing and sensory profiling serve as potent methodologies for understanding the sensory attributes of products. By conducting structured assessments, trained panelists assign intensity values to various sensory attributes. This sequential process, often organized based on the order of perception, provides a holistic insight into a product's sensory profile. Depending on the test's objectives, panelists may evaluate either a singular or multiple products within a single session, or they may be tasked with evaluating different products across successive sessions.
Within EyeQuestion, a template is available that empowers users to dynamically select the products to be evaluated during a test, even after it has deployed. Panellists can input the codes of the samples they wish to assess, and the project leader retains the flexibility to introduce additional samples throughout the study. This functionality proves particularly beneficial for shelf-life testing scenarios, where the exact number of evaluations may not be predetermined. For instance, product 1 could represent time point 0, product 2 could represent month 1, product 3 could represent month 3, and so forth. Moreover, additional products can be incorporated as necessary to evaluate additional time intervals.

Template Description

The template starts with a welcome screen that can be used for welcoming panellists, providing instructions, or asking additional questions prior to the test. The design section includes a screen with a single-line scale question type. You are free to adjust the line scale question type settings by clicking on the question type directly or add more questions/screens.
In the end screen, the template incorporates a “thank you” message, providing an opportunity for you to personalize a final message for the panelists.
Within the design settings, you can see that the template is created with a monadic design. 
Initially, this template includes one product. However, you have the flexibility to dynamically incorporate additional products even after deploying the test. Simply navigate to Design > Products and input the blinding code of the new product you wish for panelists to evaluate.
It's crucial within this template to ensure that the "Run Only Once" functionality is disabled. This is because panellists may need to access the questionnaire multiple times to evaluate additional products.

Raw Data Representation

The raw data will be displayed with each row corresponding to a product evaluated by a judge (panellist), followed by the rating of that specific product. In the sequence number column, the number equals the design that the panellist has answered the question.
