Step-by-step workflow guide

Pass an order through several zones

Move an order tote from area to area. Each area adds the items it owes.

What this fixes

Sequential zones simplify custody but can amplify imbalance, queueing, and blocked containers.

Works well whenStable zone sequence
Usually a poor fit whenHighly variable zone demand
Example

A tote moves from apparel to footwear to accessories and then goes to packing.

When this method works well—and when it does not

Works well when

  • Stable zone sequence
  • Orders with predictable zone participation
  • Conveyor, cart, or tote movement between zones
  • Clear completion confirmation at every zone

Usually a poor fit when

  • Highly variable zone demand
  • Large irregular orders
  • No accumulation space
  • Frequent rush-order overtaking

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.

Before: common problem process
  1. 1Picker owns whole order
  2. 2Crosses zones
After: better-controlled process
  1. 1Release tote
  2. 2Pick zone
  3. 3Pass or bypass
  4. 4Complete final zone

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
Fix this first

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

  1. 01

    Route only to zones with demand

  2. 02

    Define entry, completion, and bypass events

  3. 03

    Limit work-in-process between zones

  4. 04

    Balance work using measured zone content

  5. 05

    Create a recovery path for missed or damaged totes

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

What the worker seesWhat the worker should do
Queues build before one zone

Rebalance, add capacity, split work, or throttle release.

Totes visit empty zones

Correct route data and bypass logic.

Order sequence is lost

Use positive tote identity and explicit handoff events.

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

  1. Choose one realistic area, shift, and order mix
  2. Watch the current method long enough to include normal work and a busy period
  3. Test the new method using exactly the same measurement rules
  4. 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

Voodoo can indicate the active tote/task and guide puts within each zone.

When to choose something else

Container routing and conveyor control belong in work-coordination software; displays are only an execution layer.
