Problem /Opportunity Fixture’s nomenclature and control process are not standardize. It is not stated which fixture to use for a particular assembly
therefore time wasted during the search of fixtures. Non unified process between SC, MSS and LH Duplicated fixtures on inventory. Lack of fixture at the moment of the acceptance test
