Andrew Carnegie's Focused Strategy and Leadership Built Steel Industry Dominance

Andrew Carnegie, a Scottish immigrant who became the world's richest man, attributed his success to focusing on a single industry—steel—rather than diversifying early. His concentrated approach significantly reduced production costs and led to market dominance. Carnegie emphasized cost management and surrounded himself with educated talent to drive innovation, building the largest steel company of his time, which outproduced all of Britain in the 1890s.
