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.
