Diversification: This is the art of entering product markets which is different from those in which the firm is currently engaged in. This implies that diversification is when firms direct resources into a new product, that is, producing a different type of product from the existing one.

Diversification is divided into two

1. Related diversification

2. Unrelated diversification

1. Related diversification: This is the process in which the two products involved have a form of commonalities. This result to enjoying economies of scale.

2.Unrelated Diversification: This form of diversification occurs when a firm adds unrelated product lines and penetrates new markets. The new product introduced has to relation or connection with the the previous or existing product.

Unrelated diversification can be accomplished using the following methods:

1. Developing new competences to use new market opportunities.

2. Using the existing basic competences of the company and expanding from existing markets into new ones and starting new lines of production.

3. Penetrating completely new markets. Usually such opportunity can be identified as a result of the main company business.
