Experimental materials comparing individual performance implications of two decision aids: Taxonomy and tags.

Design techniques have been classified to support the selection in design processes. Two decision aids have been created. We designed an experiment to compare both decision aids (taxonomy and tags) and evaluate the influence of individuals' decision style when using a decision aid. The experiment materials included the experimental process, a training, an experimental task, and the survey questionnaire. In this method article, we describe the details of the experiment settings and use the collected data to validate the experiment. Advantages of this method include the following:•The procedure of the experiment ensured an easy-to-understand training part without any bias toward performing the experimental task and answering the survey questionnaire at the end.•The experimental process can be applied to experiments for evaluating task performance by using user interfaces with a training part before the experimental task.•The experimental task scenario and the design techniques included in the experiment can be applied in experiments with design-relevant task scenarios.
