The principles and methodology of Six Sigma are applicable to multiple industries and processes. In all cases, the primary reason these principles are implemented is to eliminate errors, to the greatest extent possible, before they happen. The only way to accomplish this is by starting with an honest assessment of the process, locating the source of the error(s), and making needed correction(s) there. By implementing solutions upstream, where the errors occur, the client will realize much greater confidence in the quality of the final products being sent to the customer. The “quality” of the final product is what the customer is paying for. Quality in this case refers to: safety, price, availability, usefulness, and effectiveness in filling the need(s) that the customer has. All these requirements must be met for the product to be successful. If it’s not safe, why buy it? If it’s too costly or not available, alternatives will be found. If it’s not useful in solving the issue, the customer won’t want to pay for it. So, why buy it?
