I was wondering if there was a vetted type of questionnaire developed for Enterprise applications that modifies the questions that may not apply to a given system.
Systems like a timesheet application are not something someone would choose to use for any other reason except they need to use it to get paid, so I doubt anyone would strongly agree to "I think I would like to use this system frequently".
For systems in already in use, when gaining a baseline measure, the question "I think I would need the support of a technical person to be able to use the system" may generate odd responses because the individuals that are required to use the system may have years of experience with it.
I would like to use the SUS to baseline where we are at before a redesign, so are there any processes/guidelines for tweaking the SUS to get reliable results in situations like this? Does a modified SUS already exist?
I am aware that similar questions have been asked (SUS Scores and Doubts),
