Business and Finance

Diversification is a corporate strategy to increase sales volume from new products and new markets. Diversification can be expanding into a new segment of an industry that the business is already in, or investing in a promising business outside of the scope of the existing business.
Diversification is part of the four main growth strategies defined by Igor Ansoff's Product/ Market matrix.
Ansoff pointed out that a diversification strategy stands apart from the other three strategies. The first three strategies are usually pursued with the same technical, financial, and merchandising resources used for the original product line, whereas diversification usually requires a company to acquire new skills, new techniques and new facilities.

"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]
