A company looking to enter the airline industry has determined that the threat of new entrants is low and the bargaining power of suppliers and buyers is high. There is a highly competitive landscape with numerous substitutions available. What tool has the company used for its industry analysis?

The company has used Porter's Five Forces model for its industry analysis. This strategic framework evaluates the competitive intensity and attractiveness of an industry by analyzing five key forces. The elements mentioned in the scenario—threat of new entrants, bargaining power of suppliers, bargaining power of buyers, threat of substitute products, and the intensity of competitive rivalry—are the exact components of this model. It helps organizations understand the underlying structure of their industry and their strategic position within it.

A. STEEPLED analysis is a macro-environmental tool that assesses Social, Technological, Economic, Environmental, Political, Legal, Ethical, and Demographic factors.
