Business is a process in which products offered by firms are competing for their respective consumers within a given context of marketplace,thus rendering business components become context-determinable.This paper explores how consumers fathom competing products into brands and why Italian Aquazzura has settled with Ivanka Trump in the legal jurisdiction of the United States? We started to dissect the product-tobrand formation process,and assessed competing products in a distance of similarity on product functionality and legally protectable design for their respective role in brand formation by consumers,and then explained why enculturation by context should be a determinant logic for product competitive advantages.In our modeling,we deductively redefine brand prominence as being to accumulate for its collective knowledge and experience κ on a common account of enculturation per a given context.Therefore,we reason that no product has brand prominence without enculturation determinacy per context because it could not exist within a single person who does not share κ commonly acceptable with others on ones etic account of enculturation conformance.We also find that product evolvement or innovation is in essence relatively proportionate with the properties and attributes per context determinacy.We provide a juxtaposing approach to analyze the threshold of similarity distance between competing offerings to prove enculturation determinant logic necessary for business,and acculturation determinant logic for international business.
