In 2003, 18 manufacturing sectors and 14 service sectors were surveyed, and as of 2017, 33 manufacturing sectors and 31 service sectors are under investigation.

NBCI models the multi-dependent causal relationship between brand factors and brand competitiveness, calculates the influence of constructs on brand competitiveness, and then calculates the influence of brand competitiveness on performance factors.

NBCI investigates brands that represent industries in the domestic manufacturing and service industries in order to indicate the level of brand competitiveness across Korean companies.
