Value Chain Analysis enables us to understand competitive challenges and to identify vertical coordination mechanisms. The term "value chain" has thus been used to characterize this interconnected, coordinated set of links and linkages that take place as products move along a continuum between primary production and the consumer. Value Chain Analysis is sometimes used interchangeably with Subsector Analysis. Others differentiate with a Subsector Analysis examining all the firms, channels and markets related to a specific product or service and Value Chain Analysis focusing on a single vertical chain of firms leading to a particular consumer market. Value Chain Analysis also often includes additional analytical elements beyond Subsector Analysis such as inter-firm cooperation, governance and geographic coverage that extends to global markets.
