proponents of the apdex standard believe that it offers a better way to "measure what matters". the apdex method converts many measurements into one number on a uniform scale of 0 to 1 (0 = no users satisfied, 1 = all users satisfied). the resulting apdex score is a numerical measure of user satisfaction with the performance of enterprise applications. this metric can be used to report on any source of end-user performance measurements for which a performance objective has been defined.
