QuickMBA / Marketing / Marketing Research. Managers need information in order to introduce products and services that create value in the mind of the customer. But the perception of value is a subjective one, and what customers value this year may be quite different from what they value next year.
Amazon River. The Amazon River, usually abbreviated to Amazon (US: /ËÃ¦mÉzÉn/ or UK: /ËÃ¦mÉzÉn/; Spanish and Portuguese: Amazonas), in South America is the largest river by discharge volume of water in the world and according to some authors, the longest in length.
The Amazon basin (the watershed of the Amazon River) is 7,050,000 km2 in area (or about 2,500,000 miles2), and covers about 40% of South America. Of this area, approximately 5,000,000 km2 is (or was) covered by high tropical rainforest, with the remainder covered by savannah (campo) or scrubby woodland (cerrado).he Amazon basin covers significant portions of the countries of Brazil, Peru, Colombia, Ecuador, Venezuela and Bolivia, though the major part of the watershed lies within Brazil. The next largest tropical watershed, that of the Congo River, at 3,690,000 km2, is only half the size of the Amazon basin.
