Value migration

In marketing, value migration is the shifting of value-creating forces. Value migrates from outmoded business models to business designs that are better able to satisfy customers' priorities. Marketing strategy is the art of creating value for the customer. This can only be done by offering a product or service that corresponds to customer needs. In a fast changing business environment, the factors that determine value are constantly changing.
Three stages.
The value chain is the sum of all activities that add utility to the customer. Parts of the value chain will be internal to the company, while others will come from suppliers, distributors, and other channel partners. A linkage occurs whenever one activity affects other activities in the chain. To optimize a value chain, the linkages must be well coordinated.
The calculation of value migration is more difficult than it would at first seem. Value is perceived by customers and, as such, is subjective. This is very difficult to measure so "relative market value" of the firm is used as a proxy. Relative market value (defined as capitalization divided by annual revenue) is used as an indication of the firm's success at creating value.
