Second method is my personal approach..
If the design is developed for the local population.
(The design should be simple in human factor complexity & tasks; it’s your call.)
Create the mockup based upon applied anthropometry data.
Then search for 5th (female) & 95th (male) percentile persons in your vicinity (may be in your or client’s office.)
Ask them to perform the task. Video-record the process. Check their feedback. Refine the design.
May be..human factor products designing setups should employ 5th (female) & 95th (male) percentile persons for their feedback
