Some companies use the same control systems for each unit or operation worldwide. For example, Starbucks, Kentucky Fried Chicken, or McDonalds apply the same rigid quality controls throughout all aspects of their organizations, even as they expand internationally. Why would a company such as these impose rigorous corporate quality standards, regardless of the country it operates? what modifications in these quality standards if any, should the company permit because of differences across nations or regions of the World? why is the company allowing these modifications to occur? Short and concise answer please.
