Take the following as truth: Xerox achieves this by building production representative prototypes and by requiring suppliers of key components and subassemblies to produce an adequate sample of parts to demonstrate the suppliers' processes can be controlled, usually before the parts are incorporated into the prototypes.
Then the following statement: "By requiring their suppliers to produce samples, Xerox ensures that they will not run out of critical parts that they need to make their products." is true, false, or inconclusive?
Answer: Inconclusive
