Study Notes

Evaluating Products

Different evaluation techniques assess how a product performs in various aspects.
Products can be functional but not appealing due to appearance or cost.
Evaluation techniques measure factors like function, ergonomics, aesthetics, costs, and value.

Evaluation Techniques

Evaluation Presenting: Surveys gather opinions on the product using a scale and allowing comments for explanations. Results can appear as bar graphs or pie charts to show averages.
Questionnaire: This method works best with those who have interacted with the product. More responses lead to more accurate results. Data visualization (like spider web diagrams) show detailed results; additional written comments from participants are valuable.
User Trip/Trial: Observing users interact with the product and recording their impressions. Gathering pre-defined data about potential issues or areas for improvement during the trial. Data is usually presented in written format in separate sections categorized by relevant design factors.
