The Discovery Survey assesses an individual's natural ability in the 10 Plum Talents:
Talents are composed of a specific combination of competencies. Each competency is a specific combination of 12 traits.
Talents are calculated by combining traits using an algorithm developed by experts in industrial/organizational psychology.
The traits themselves are measured using techniques that are supported by years of research on personality, cognitive ability, and social intelligence.* This includes using a forced choice approach, giving realistic work situations, and even using puzzles.
