Global parts procurement presents challenges to any product designer. If a component is sourced from multiple suppliers, how do you keep track of these suppliers from initial design to production, especially in a global manufacturing environment where products are made in multiple locations? Do you really have the right manufacturing and process controls to manage such an environment? The unit submitted to a certified test facility had a specific supplier but is there assurance that other suppliers will perform the same during testing? If not watched carefully, these variables could wreak havoc with product certification and regulators worldwide.
