B sounds off, summative doesn't just need experts.

I feel like I mixed up the definitions in my studies; I thought formative evaluations involved user tests, but now I'm questioning that.

I practiced a question similar to this, and I think option C sounds right since it mentions assessing outcomes for summative evaluations.

I remember something about summative evaluations being more about expert reviews, but I can't recall the specifics.

I think formative evaluations are more about improving the design, while summative ones look at the final results, but I'm not entirely sure.

Ah yes, I remember now - formative evaluations are focused on improving the design, while summative evaluations are about assessing the final usability of the product. I feel pretty good about this one.

Hmm, I think the key difference is that formative evaluations use actual users to get feedback and make changes, while summative evaluations rely more on expert reviews. I'll make sure to double-check that in the exam.

I'm a bit confused on the distinction here. Is it that formative is more about the process and summative is more about the end result? Or is it the other way around? I'll need to review my notes to make sure I understand this properly.

Okay, let's see. Formative is when you evaluate the design during development to make improvements, and summative is when you evaluate the final product to see how well it meets the requirements. I'm pretty confident I've got that right.

Hmm, I think this is asking about the difference between formative and summative usability evaluations. I'll need to remember that formative is focused on improving the design, while summative is more about assessing the final outcome.
