KPIs, typically derived from website analytics, are important in UX evaluation. However, most UX evaluation comes from direct interaction with customers through observations, interviews, and questionnaires as indicated by Alves, Valente, and Nunes (2014). KPIs are mainly used for future evaluation and pinpointing areas of concern. Direct interaction with the product and customer observation are vital, underlining the necessity of UX research.
When evaluating UX, one needs to approach with caution and experience due to the complexities of questionnaire design, administration, and a profound understanding of survey analysis (Groves, Fowler, Couper, Lepkowski, Singer, and Tourangeau, 2009). Now, let's explore how we can measure UX.
- Observations: Direct user observations provide insights into behaviors and issues.
- Interviews: One-on-one interviews offer understanding of user experiences.
- Usability Testing: Identifies usability issues through user task performance.
- Surveys: Gives quantitative data on user perceptions and satisfaction, employing tools like the User Experience Questionnaire and System Usability Scale.
- Experience Prototyping: Enables users to interact with the design for feedback and refinement.
