Ansoff's product / market matrix
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.
