[Sigia-l] Measuring user satisfaction and intuitiveness of a system

[Polka, Ronald]

All,

 

We have a system that was designed largely without utilizing a
user-centered design process. We're constantly facing challenges on how
to validate our designs and the UI of the system. Some stakeholders
within the organization think the user experience of the system is
intuitive and satisfactory while others think the exact opposite.

 

My question: is there a standard measure I can use to validate whether
or not our user base finds their experience with the system in general
as satisfactory and intuitive.

 

I've come across the SUS, Microsoft's Desirability Toolkit, QUIS, USE,
and other measures out there but it seems these measures are designed to
be used in conjunction with a usability testing session focused on
specific screens in the system. I'd like to measure the system as a
whole so as to gauge where we stand today with our users.

 

Any thoughts or comments? Has anyone run into a similar scenario or
situation - if so what did you do?

 

Thanks,
