Relying on one supplier or partner

When one supplier or partner holds a critical input, they can reset the terms. Research on supplier dependence and case studies, from 1882 to today.

What is usually going on

A single supplier or partner can be efficient, until they raise prices, change terms or cannot deliver. The test isn’t whether a second option exists on paper, but whether it would work when the first one fails.
