4.6 Perform Usability Test
It is always good to perform a usability test for new applications. People who have not been involved
in the design or development of the application tend to notice potential usability problems often not
obvious to those who know the design by heart. Usability tests should always be performed as early
as possible in the development process. Any necessary changes resulting from the tests can then be
implemented within the development schedule. Try to recruit users who are representative of the end
users of the application, and try to conduct the usability test on a smaller scale, if the schedule does
not allow for extensive testing.
