VOLLEYBALL INFORMATION SYSTEM (VIS)

FIVB’s VIS is used to calculate points scored for individual skills of volleyball players. The players who win seven different categories for particular skills are rewarded with the Most Valuable Player (MVP) title at the end of a tournament. This system is used to identify top players in all FIVB events.
