The Race Among Rivals for Industry Leadership Is More Likely

The race among rivals for industry leadership is more likely to be a marathon rather than a sprint when,

A) new industry or market segments are yet to be developed and create altogether new consumer demand.
B) fast followers find it easy to leapfrog the pioneer with even better next-generation products of their own.
C) the market depends on the development of complementary products or services that are currently not available, buyers have high switching costs, and influential rivals are in position to derail the efforts of a first-mover.
D) entry barriers are high, substitute products or services are readily available, and buyers are prone to negotiate aggressively for better terms and lower prices.
E) there are nearly always big advantages to being a slow mover rather than an early mover, especially as concerns avoiding the "mistakes" of first or early movers.
