For core questions, respondents had to rank minimum, perceived and desired expectations on a scale from 1 to 9
How do we interpret these scores?
Perceived Score
5.0
Adequacy gap:
-1.0
7.0
Minimum
Desired 6.0 8.0
Zone of tolerance
Adequacy gap: +1.0
Minimum – number we don’t want to go below
Desired – what we aim for; also a measure of importance of the issue to the user
Perceived – how we are doing (in users’ perception)
