We strive for flawless products and are thereby striving for the perfect production process. Root cause analyses are one tool that we always perform of non-conformities but “Zero defect” takes it a step further. The principle is that non-conformities are not allowed to happen at all. Then we need to be in front of the things happening. Our processes are analyzed and clear work descriptions are made visible to all operators where the method shall be close to bullet proof when it comes to safe operating and non-conformities.
