To create the ranking, the HRO Today research team collected available public data from a representative list of 40 established benchmarking and ranking programs in the identified categories. This allows researchers to generate a score based equally on the depth and breadth of outside recognition and internal recognition.
To generate the score, researchers examine the number of lists identified a particular company appears on and their relative ranking where appropriate., This information is then aggregated and weighted to create the final score, which produces the ranking.
