Questions: Limitations of Porter's Five Forces model include Porters model is inherently static, representing only aspects of the present day. The Five Forces model should be used at the broader level of an entire industry; it is not designed to be used at a smaller group or market level. It's a thinking exercise to demonstrate the subjective attractiveness of a given industry landscape. It is not designed to decide optimal industries with certainty. All the choices are correct.

The answer is all the choices are correct.

This is correct because Porter's Five Forces model provides a snapshot of the competitive environment at a specific point in time. It does not account for changes over time, such as technological advancements, regulatory changes, or shifts in consumer preferences.

This is also correct. The model is intended to analyze the competitive forces within an entire industry rather than focusing on specific segments or niches within that industry. Applying it to smaller groups or markets may not yield accurate or useful insights.

This is correct as well. The Five Forces model helps to understand the competitive dynamics and attractiveness of an industry, but it does not provide definitive answers about which industries are the best to enter. It is a tool for analysis and strategic thinking rather than a prescriptive decision-making framework.

Therefore, all the choices are correct.
