Not sure if just one test is enough to judge usability.

Looks like the scores are above average, so maybe we’re good?

I believe heuristic evaluations can help clarify issues in usability, especially if the SUMI results are vague, but I'm uncertain if that's the right next step here.

If the scores aren't showing high user satisfaction, I feel like we should definitely consider more usability testing, but I'm not clear on the best approach.

I think we practiced a question where a large standard deviation meant we needed to dig deeper, but I can't recall the exact implications for the SUMI test.

I remember discussing how high SUMI scores might indicate good usability, but I'm not sure if we should always rely on that alone.
