Which term best describes the evaluation of a product through casual feedback?

The term that best describes the evaluation of a product through casual feedback is informal testing. Informal testing typically involves gathering insights and opinions from users in a more relaxed, spontaneous setting rather than through structured methods. This can include things like asking users for their thoughts while they use the product or observing their reactions, which allows for immediate and honest feedback.

This approach is beneficial because it captures genuine user experiences in real time, providing designers with valuable qualitative data to improve the product. Informal testing does not follow rigid protocols and often allows for a broader range of feedback that can be more representative of actual user interactions.

Formal testing, in contrast, involves systematic procedures and controlled conditions, which do not align with the idea of spontaneous feedback. Quantitative analysis focuses on measurable data, often derived from large sample sizes and statistical methods, rather than casual user observations. Competitor analysis entails a comparison of a product with those of competitors, which is separate from user feedback on a specific product experience.
