The regulatory bodies in any country be it for the government and trade and any profession, they are put in place to harmonize any practice related to that . For international trade we have International Organization for Standardization and its affiliates but when it comes to the regulation of professions , most practices are localized e.g. there is no one body that regulates all engineers, engineering technologist etc. in the world. DO you think there is need to harmonize regulation of professions to allow people work anywhere globally?
