As others have stated, the quality department must work with other departments in order to complete its main function. As such, it is important to make sure that positive interdepartmental relations are maintained. That means that each department should understand and respect the quality department and vice versa. Once that is established, the quality department must be active in being involved with the activities of the other department, as well as anticipate and report future issues they think might happen. That way departments such as the R&D department can be prepared should the issues arise or have a back up method in place. These preventive measures may take some extra time at the beginning but can prevent time consuming and costly mistakes from being made. Early correspondence will also foster a more familiar relationship. This will make it easier for departments to consult with the quality department before making any important decisions.
