COFE® WES is VARGO®’s real-time, pull-based Warehouse Execution System. It sits between the system of record and operational resources, continuously matching work to available capacity across people, automation, and equipment.
Instead of releasing work in fixed waves, COFE® continuously releases work as capacity becomes available, routing orders based on what is happening on the floor now.
The contrast is easiest to see against traditional WMS execution.
| Traditional WMS execution | COFE® WES |
|---|---|
| Work released in scheduled waves | Work released as capacity opens |
| Decisions made up front | Decisions continuously re-evaluated |
| Capacity imbalances addressed after release | Work matched to live floor conditions |
| Idle time between waves | Labor and equipment stay consistently fed |
| Downstream processes can become overloaded | Flow stays balanced across the operation |
COFE® continuously reads what is happening across the operation and uses live capacity to determine how orders should be routed. Instead of pushing work according to a predetermined schedule, the system pulls work forward only when the next step is ready for it.
COFE® continuously monitors picking, sortation, packing, and other execution points to identify where capacity is available.
Work is prioritized based on order priority, inventory location and volume, and current operating conditions.
Work is released only when the next station is ready for it — not on a fixed schedule.
As work finishes and floor conditions change, COFE® evaluates the next decision based on what is happening now.
By releasing and routing work based on live capacity, COFE® keeps labor and equipment consistently supplied, reduces congestion between process steps, and allows priorities to shift without losing control of service commitments.

COFE® combines a configurable execution engine, system-wide orchestration, and a proven implementation approach designed to make continuous flow work in the live operation.
COFE® has a proven engine at its core — but routing, sequencing, capacity rules, and automation logic are configured around each fulfillment environment rather than forcing the operation into a packaged workflow.
COFE® coordinates work across people, automation, and existing systems rather than optimizing a single machine or process in isolation. Its equipment-agnostic architecture allows different technologies to operate within one execution model.
Moving to continuous flow changes how supervisors and teams run the operation. VARGO® builds that transition into the deployment through role-specific training, hands-on testing, and floor-level support through stabilization.
