Final answer:
In business, 'mobility barriers' are industry-specific factors that create separation between strategic groups primarily due to barriers to entry, which can be government-enforced or natural within the market.
Step-by-step explanation:
Industry-specific factors known as mobility barriers separate one strategic group from another. These barriers are essentially barriers to entry that can be of legal, technological, or market nature, and they discourage or prevent potential competitors from entering a market. An example of this would be the significant brand recognition and marketing strength required to compete with established players in an oligopoly, such as Coca-Cola or Pepsi in the soft drink industry.Barriers to entry can be government-enforced, like regulations or licensing requirements, or they can arise naturally within the market, such as through large economies of scale or control over a unique resource. Oligopolies are market structures where a few firms dominate, often characterized by high entry barriers that lead to strategic decision-making based on the behavior of other firms within the market.
