Once a product has had its first approval, every design change, supplier proposals included, is assessed for its possible effect on fit, form, function, performance and durability, is validated against customer requirements and is approved inside the organization before it is put into production. If the customer requires it, the organization first obtains documented approval from the customer, or a documented waiver. For products that contain embedded software, the change record documents the revision levels of both the software and the hardware.
