Map frame

What to do: Attach or sketch a scaled layout.

Area / processUse the real warehouse name or location code.Example: Zone A, locations A-01 through A-48Map scaleShow how drawing distance converts to real distance.Example: 1 inch = 20 feetObservation periodRecord the exact start and finish time or number of complete tasks observed.Example: 9:00–10:30 a.m.; 20 complete ordersWorker / equipmentRecord the worker role and the cart, vehicle, or device used for the route.Example: Day-shift picker · eight-position cartStart and end pointsName the physical point where the traced route begins and ends.Example: Starts at cart staging; ends at packing lane 2

Route trace

What to do: Number every stop and connect actual movement.

This section is a list.Use one row for each task, observation, test, person, field, or requirement. Add more rows when needed.

Summary

What to do: Convert the drawing into a decision.

Total distance / cycleEnter the complete route distance for one task and include the unit.Example: 620 feet per completed orderBacktrack distanceDistance spent returning to an earlier point on the route.Example: 170 feet per orderRepeated locationsUse the real warehouse name or location code.Example: Zone A, locations A-01 through A-48Unsafe crossingsList route crossings that create a vehicle, pedestrian, visibility, or load risk.Example: Picker crosses the forklift refill lane four times per orderCandidate relocationName an item, printer, supply, or station that might move.Example: Move label printer beside packing station 2Expected effect to testState the measurable result expected from the proposed route or relocation change.Example: Move the printer and reduce walking by at least 120 feet per order
