I’m a bit confused about D; it seems more about satisfaction than operability, but I could be wrong.

I’m not entirely sure, but I feel like B could also be relevant since it measures how well tasks are achieved.

I remember discussing how task completion rates are crucial for operability, so I think A might be a good choice.

I'm a little confused by the wording of these options. Are they all valid acceptance criteria, just for different usability aspects? I'll have to read through them again carefully to make sure I'm choosing the right one for operability.

Okay, I've got this. Operability is about how well users can actually complete tasks, so the correct answer is B - the mean extent to which each task was completely and correctly achieved. That's a direct measure of operability.

Hmm, let me think... I know there's End Post and Corner Post, but I can't remember the third one. I'll have to think this through carefully.

I'm just hoping the test has a multiple choice option for 'All of the above' - that would make this a breeze!

Option B seems like the most comprehensive approach to me. Measuring the extent to which each task is achieved gives a better overall picture of usability.

I agree with Denise. If tasks are taking too long to complete, it could indicate issues with operability.
