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 believe option D) SUMI user satisfaction score could also be relevant for operability, as user satisfaction is important for usability.

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

Haha, I bet the test creator is just trying to trip us up with all these options. I'm going with C - time to completion is the way to go!

I see your point, but I still think C is the way to go - mean time taken to complete each task.

I'm not sure about that. Wouldn't the percentage of participants who completed each task correctly (option A) be a better measure of operability?

I think option C is the best choice for operability. Measuring the mean time taken to complete each task is a key indicator of how user-friendly the system is.

Mean extent to which each task was completely and correctly achieved, scored as a percentage, could also be a valuable acceptance criteria for operability.
