Functional Positives
Well... the system seems to work Regularity of task performed Minimal learning curve with system Regardless of errors, if enough buttons are pushed, a positive result will be reached.

but maybe I’m just being nice.
Functional Negatives
Page titles are misleading Graphics are confusing Too many haptic choices Directions don’t afford easiest solution No breadcrumb trails Lack of user awareness of location Confusing taxonomy, i.e. “transaction”

General Conclusions
System is somewhat usable Significant room for improvement Graphics are poor and relate badly Too many choices of physical buttons related to too few on screen choices On screen reading is too much for regular time-on-task

Design Recommendations
Label pages with appropriate titles Use graphics or words, not both. If both graphics and words are used, combine as buttons Change to a touch screen, rather than multiple button panels and a screen Clarify actions so that one gesture affords an intuitive action Provide location awareness to users, such as page transitions or a breadcrumb trail Clean up taxonomical issues Combine screens when possible.
