Hogan Leadership Inventories.  Three primary inventories are used to help assess best fit in current position or selection of candidates for job movement (lateral, upward). The assessments are validated for use in hiring. Hogan Personality Inventory (HPI) – a state of the art measure of normal personality based on the Five Factor Model. Hogan Development Survey (HDS) – an inventory designed to measure career-derailing tendencies including 11 patterns of behavior that impede work relationships, hinder productivity or limit overall career potential. Motives, Values, Preferences Inventory (MVPI) – an instrument that reveals a person’s core values, which are key to work and life satisfaction.
