Which of the following is not one of Porters five competitive forces?
A
Bargaining power of suppliers
B
Threats of new entrants and barriers to entry
C
Threats of technological advances
D
Threats of substitutes
Correct Answer: Threats of technological advances
Threats of technological advances is not one of Porters five competitive forces. Porter's five forces include three forces from 'horizontal' competition--the threat of substitute products or services, the threat of established rivals, and the threat of new entrants--and two others from 'vertical' competition--the bargaining power of suppliers and the bargaining power of customers.
