Question

What is the theory of standardization?

Answer 1

in industry, standardized and interchangeable parts, a concept developed by Eli Whitney, means that a finished product can be made or repaired from component parts that are interchangeable. standardization also implies that the number of different and unique parts should be reduced to a handful of sizes. For example, assembling a product from just 9mm screws at every attachment point reduces error and simplifies inventory control.
