Uncontrolled document, 3L 5*Why - Coggle Diagram

- - - - 1.1.1
        The roll angle of the final assembly was inaccurate. (out of tolerance).
        
        1.1.1.1
        Due to warping/springback of mainly the injection molded Arm Lower, the roll angle of the final assembly is out of tolerance.
        
        1.1.1.1.1
        In the GD&T of document number D070890, we find clampingpoint A3, which doesn't reflect the mating surfaces of the powerfold.
        
        1.1.1.1.1.1
        The supplier didn't carry out a compensation loop (or did it wrong) to adjust for the springback of the part.
        
        1.1.1.1.1.1.1
        The quality has been accepted by the Quality department of Stoneridge Orlaco
        
        Check if we can pusuade the supplier to modify it's dies.
        
        Update the 2D-drawing to have a GD&T which reflects reality.
    - - 1.2.1
        The change management document is limited to the introduction of part changes and assembly sequence changes.
    - - 1.3.1
        The production team didn't notice the obsolete and uncontrolled document
        
        1.3.1.1
        
        Optional: create a one point lesson to inform operators about the ability to inform the production lead of uncontrolled documents.
        
        The production team might be insufficiently aware of their ability to inform the productionlead of inconsistencies in the production line
    - - 1.4.1
        The screwing sequence is introduced as a supposed countermeasure for spread in the yaw and roll.
        
        1.4.1.1
        The sequence introduced because we assumed it was the rootcause of our variation
        
        1.4.1.1.
        A proper rootcause analyis hasn't been performed
        
        1.4.1.1.1
        Because of customer pressure
      - 1.4.2.
        Orlaco Global requested to introduce paper information carriers
        
        1.4.2.1
        To be able to present more information at once such as:
        
        Q-alerts
        
        assembly instructions
        
        1.4.2.2
        to conform with global standards

        Why are inspections after SOP not taking into consideration uncontrolled documents
        Normally process changes are done before start of production. in case there are changes made to existing processes, this will be done with change management.
        
        1.1.1.1
        Why did the team not used change management?
        In the current department instruction it says that change management is done for changes to the part or to the assembly sequence.
        
        Implement a Robust Change Management System: Strengthen change management processes to ensure all changes are documented, reviewed, and integrated into the existing quality and inspection frameworks efficiently and comprehensively.

        Revise and Update Inspection and Quality Control Processes:
        Ensure that any process or equipment changes are immediately followed by a review and update of inspection and quality control processes to include these changes.
