One worker picks freezer items and another picks room-temperature items; both totes meet at a clearly marked combine point.
When this method works well—and when it does not
Works well when
- Large product range or building footprint
- Distinct storage media or handling skills
- Orders commonly span several zones
- Enough volume to staff zones deliberately
Usually a poor fit when
- Small compact pick area
- Very low order volume
- Extremely uneven demand with no dynamic staffing
- No controlled consolidation method
Show exactly what happens at each step
Write down actions that someone can see or confirm: what the worker does, what moves, who owns the next step, and what happens if something goes wrong.
- 1One picker crosses building
- 2Long routes
- 3Complete order
- 1Release by zone
- 2Pick compact work
- 3Consolidate zones
- 4Verify complete order
Get these basics right before adding technology
- One named person owns the process, and everyone agrees what one task includes
- Current time, accuracy, problem, and volume numbers collected using written rules
- One named person corrects product and location information
- A written backup method and a clear path for getting help
If workers cannot reliably identify the item, order, or location, correct that problem before expecting new guidance equipment to improve accuracy.
Step-by-step procedure
- 01
Define zones around work content, not equal square footage
- 02
Measure demand by zone and hour
- 03
Choose simultaneous or sequential handoff logic
- 04
Control order identity at every transition
- 05
Expose missing-zone work and aging
Information the process must track
For each task, decide what item or order is being worked, where it comes from, where it goes, how much is expected, how the worker confirms completion, what happens when something goes wrong, and which system records the final result.
Technical notes for the warehouse software or IT team
Use one unique task ID. Re-sending the same message should not create a duplicate move or pick. Keep a way to compare records and repair differences when messages are delayed, repeated, or missed.
Decide what workers should do when something goes wrong
Reslot, resize zones, cross-train, or release dynamically.
Separate missing work, completed work, and problems visibly.
Fix balance or formalize dynamic zones rather than hiding the workaround.
Numbers to watch
Before the test starts, write down what is counted, what it is divided by, when the clock starts and stops, what is excluded, and where the data comes from. Keep those rules the same through the test.
Test it on a small scale before a full rollout
Trial steps
- Choose one realistic area, shift, and order mix
- Watch the current method long enough to include normal work and a busy period
- Test the new method using exactly the same measurement rules
- Review every problem and worker workaround before expanding the change
What must be true before rollout
- The target output is maintained for one full, realistic shift
- Accuracy and problem recovery meet the written target
- New workers can follow the process without unwritten tips from experienced workers
- The backup method works, and the team can return cleanly to the normal process
Voodoo is one possible way to guide the work—not the answer to every problem.
Where it may help
Displays can guide zone work and consolidation positions without fixed wiring, including directional arrows across multiple locations.

Guidance does not solve chronically unbalanced zone design or weak release logic.
