b) learn about whether or not you'd see any particular issues in using
SUS for website usability evaluation.
My experience over the years, albeit based on a limited number of use
cases, indicates that SUS scores pretty much correlate with what you'd
find out in user testing sessions too (referring to respective site's
general usability, and how satisfied users would claim they are).
However, you might have some additional thoughts and insight for which
I'd be very thankful.
