Almost the entire distribution chain is linked together by technology in every phase imaginable. The larger distribution networks report entire complex shipments arriving at their dock doors with close to 99 percent accuracy rates. These advances are making the process of counting in inventory no longer cost-effective. The time and effort spent trying to find the one miscounted part or supply is simply no longer worth the labor. Almost everything is scanned and rescanned countless times before it ever leaves the main distribution center, and the accuracies that can be achieved today are astounding.
