After improvements, non-value added activities decreased in average from 36.78%  to 20.64%.  Balance delay decreased in average from 23.46% to 9.04% and defect rate decreased in average from 5.08% to 3.71%. As a result, the productivity drawer (2PLC) increased 67.86%, the productivity cabinet (3HL) increased 68.42%, the productivity beverage counter (3CD) increased 63.04%, the productivity food counter (CF90) increased 64.44% and the productivity shelf (37A) increased 62.79%.
