Exercise 2 As a Factory Manager you decide to convene a meeting to find out the causes of the container seal failure. During the meeting, the problem cards were examined and additional causes of leak failure were identified, which are listed below: 1. The leak control equipment was not correct checked and verified 2. The condition check program of the leak control equipment was insufficient 3. Errors in the visual quality control of the containers (compliant containers were marked as non- compliant) 4. Low quality tinplate 5. Major supplier could not supply tinplate of required specifications resulting in unsuitable material being received 6. The equipment of the tinplate supplier was insufficient 7. Low quality welding material 8. Low quality internal container insulation material 9. Instability in gluing 10. Impacts on containers when moving with the pallet truck 11. Excessive workload of pallet truck operators 12. Poor cutting of the tin sheet in the cutter 13. Insufficient equipment maintenance program 14. Wrong temperature setting in the welding stabilization oven 15. Errors during the tightness test of the containers (containers that were not watertight passed the special inspection device as compliant) Construct the "cause-effect" diagram (Ishikawa), classifying the above causes into the following four (4) main categories: Man (Employees), Machine (Equipment), Method (Procedures), Material
