Manufacturing Systems UCL = process mean + 3 sigma LCL = process mean – 3 sigma SPC: large volume production– cannot measure every item continual monitoring - prevents poor quality X-bar chart – mean comparison R chart – range values
Manufacturing Systems Plan Analyse current situation Gather data Use problem solving tools to unravel problem Suggest solution Do Put trial or pilot solution in place Usually on some small part of the process
Manufacturing Systems Study Critically evaluate trial solution Examine problems or opportunities Act Implement solution in a standardised manner: Formally adopt as standard procedure Fully document
