  • Establish satellite storage areas to decrease travel time
  • Use a groundskeeper as a “runner” working with the material supervisor
  • Redraw boundaries for all (4) corrals to reduce travel time

  • Work order costs were reduced from 30% to 92%
  • Time to process a work order was reduced from 24 hours to 1.81 hours
