Differentiation is a source of competitive advantage. Although research in a niche market may result in changing your product in order to improve differentiation, the changes themselves are not differentiation. Marketing or product differentiation is the process of describing the differences between products or services, or the resulting list of differences. This is done in order to demonstrate the unique aspects of your product and create a sense of value. Marketing textbooks are firm on the point that any differentiation must be valued by buyers (e.g. ). The term unique selling proposition refers to advertising to communicate a product's differentiation .
In economics, successful product differentiation leads to monopolistic competition and is inconsistent with the conditions for perfect competition, which include the requirement that the products of competing firms should be perfect substitutes.
The brand differences are usually minor; they can be merely a difference in packaging or an advertising theme. The physical product need not change, but it could. Differentiation is due to buyers perceiving a difference, hence causes of differentiation may be functional aspects of the product or service, how it is distributed and marketed, or who buys it. The major sources of product differentiation are as follows.
Differentiation primarily impacts performance through reducing directness of competition: As the product becomes more different, categorization becomes more difficult and hence draws fewer comparisons with its competition. A successful product differentiation strategy will move your product from competing based primarily on price to competing on non-price factors (such as product characteristics, distribution strategy, or promotional variables).
Most people would say that the implication of differentiation is the possibility of charging a price premium; however, this is a gross simplification. If customers value the firm's offer, they will be less sensitive to aspects of competing offers; price may not be one of these aspects. Differentiation makes customers in a given segment have a lower sensitivity to other features (non-price) of the product .
