In the context of a single ease-of-use question, everything that’s above 5 would be considered a good ease-of-use score.
However, keep in mind that this a an entirely subjective evaluation. What constitutes a “good” score can also depend on your industry, target audience, and the specific product or service you’re evaluating.
Establishing benchmarks and comparing your scores to industry standards or competitor products is essential to determine the adequacy of your ease of use score.
