Correct, in a ROWE (for us; obviously if you're a 7/11 you have open hours, etc.), there's no such thing as "work hours". But, for the same reasons that we have short iterations in scrum, we time-box results to a week so feedback is early and often, and we can continually course-correct.

With our implementation of ROWE, there's no such thing as an "annual performance review" because you essentially get one every week. We have periodic salary review (quarterly) to see if you need adjusted (salary is based on a semi-objective tech ladder we've devised) but otherwise there's no "Let's meet every 12 months so I can check off 'meets expectations' and give you your cost-of-living adjustment"
