Marketing

"Porter five forces analysis is a framework for industry analysis and business strategy development. It draws upon industrial organization (IO) economics to derive five forces that determine the competitive intensity and therefore attractiveness of a market. Attractiveness in this context refers to the overall industry profitability. An "unattractive" industry is one in which the combination of these five forces acts to drive down overall profitability. A very unattractive industry would be one approaching "pure competition", in which available profits for all firms are driven to normal profit.
Three of Porter's five forces refer to competition from external sources. The remainder are internal threats.
Porter referred to these forces as the micro environment, to contrast it with the more general term macro environment. They consist of those forces close to a company that affect its ability to serve its customers and make a profit. A change in any of the forces normally requires a business unit to re-assess the marketplace given the overall change in industry information. The overall industry attractiveness does not imply that every firm in the industry will return the same profitability. Firms are able to apply their core competencies, business model or network to achieve a profit above the industry average. A clear example of this is the airline industry. As an industry, profitability is low and yet individual companies, by applying unique business models, have been able to make a return in excess of the industry average.
Porter's five forces include - three forces from 'horizontal' competition: the threat of substitute products or services, the threat of established rivals, and the threat of new entrants; and two forces from 'vertical' competition: the bargaining power of suppliers and the bargaining power of customers.
This five forces analysis, is just one part of the complete Porter strategic models. The other elements are the value chain and the generic strategies." [Porter five forces analysis. Wikipedia]

"The six markets model.
Christopher, Payne and Ballantyne (1991) from Cranfield University goes further. They identify six markets which they claim are central to relationship marketing. They are: internal markets, supplier markets, recruitment markets, referral markets, influence markets, and customer markets.
Referral marketing is developing and implementing a marketing plan to stimulate referrals. Although it may take months before you see the effect of referral marketing, this is often the most effective part of an overall marketing plan and the best use of resources.
Marketing to suppliers is aimed at ensuring a long-term conflict-free relationship in which all parties understand each other's needs and exceed each other's expectations. Such a strategy can reduce costs and improve quality.
Influence markets involve a wide range of sub-markets including: government regulators, standards bodies, lobbyists, stockholders, bankers, venture capitalists, financial analysts, stockbrokers, consumer associations, environmental associations, and labor associations. These activities are typically carried out by the public relations department, but relationship marketers feel that marketing to all six markets is the responsibility of everyone in the organization. Each market may require its own explicit strategies and a separate marketing mix for each." [Relationship marketing. Wikipedia]

"A value chain is a chain of activities that a firm operating in a specific industry performs in order to deliver a valuable product or service for the market. ...
The concept of value chains as decision support tools, was added onto the competitive strategies paradigm developed by Porter as early as 1979. In Porter's value chains, Inbound Logistics, Operations, Outbound Logistics, Marketing and Sales and Service are categorized as primary activities. Secondary activities include Procurement, Human Resource management, Technological Development and Infrastructure." [Value chain. Wikipedia]
