Final answer:
An undifferentiated targeting strategy will likely fail in a market where consumers have heterogeneous needs due to the necessity of product differentiation that addresses various consumer preferences.
Step-by-step explanation:
The undifferentiated targeting strategy will likely not be successful if people within the market have heterogeneous needs. This strategy assumes a uniform market where a single marketing mix can satisfy everyone's needs. However, when it comes to markets characterized by a high degree of product differentiation, such as in monopolistic competition, consumers' desires vary significantly, which makes an undifferentiated approach less effective. Brands that excel in such markets, like Coca-Cola or Pepsi, have had to heavily invest in branding and marketing to create a powerful brand name. When products are significantly diffentiated, it necessitates targeted marketing strategies that cater to the diverse preferences and needs of the market segments. Hence, in markets with varied customer needs and a high degree of product differentiation, an undifferentiated strategy is unlikely to lead to success.
