The appraisal gate has three major goals: 1) confirm the most
important EDIs to be fully analyzed in the diagnostic stage and to be
considered in the proposal of solutions; 2) plan for the prototyping
stage by defining how and when prototyping will take place; and 3)
call for volunteers for the prototyping stage. The results from the
questionnaire and ergonomist observations lead to the diagnosis
and subsequent proposal of solutions, testing and validation stages.
