Warehouse Management System (WMS) Support

WMS programs don't fail because the software is wrong. They fail because inventory accuracy, process design, user adoption, and integration stability don't get the discipline they require.

A WMS touches everything: receiving, putaway, slotting, picking, packing, shipping, inventory control, labor management, and often automation. When programs break, it's rarely one thing. It's the compounding effect of data issues, untested edge cases, weak cutover planning, and users who weren't prepared for operational reality.

BaszGroup supports organizations through WMS rollouts, upgrades, stabilization, and recovery when systems don't land as planned.

How WMS Is Used Across Industries

Different industries use WMS in different ways. The approach has to match operational reality.

📦

3PL & Logistics Providers

Multi-client operations with segregated inventory, client-specific processes, complex billing, and zero tolerance for downtime. WMS must support parallel operations and rapid client onboarding.

🛒

Consumer Packaged Goods (CPG)

Retail compliance pressure, omnichannel fulfillment, pack hierarchies, and high-velocity operations. WMS must handle OTIF requirements, ASN accuracy, and promotional spikes.

🏭

Industrial & Manufacturing

BOMs, kitting, line-side replenishment, work-in-process tracking, and quality holds. WMS must integrate tightly with MES and support complex material flows.

🥬

Grocery & Food

FEFO rules, temperature zones, expiration tracking, and shrink control. WMS must enforce rotation discipline and support cold chain integrity across the entire flow.

⚕️

Medical & Regulated Products

Lot traceability, serialization, quarantine and release workflows, audit trails, and validation requirements. WMS must be Part 11 compliant and support recall readiness.

Common Challenges

Where WMS Programs Break

Challenge 1

Item master and location data are not warehouse-ready

  • UOM conversions are inconsistent or missing, breaking picks and replenishment
  • Dimensions and weights are wrong, causing slotting and cartonization failures
  • Pack hierarchies don't reflect how product actually moves
  • Location types and attributes don't match physical constraints
  • ABC classifications and velocity codes are outdated or nonexistent
Symptom
"The system keeps sending us to the wrong locations."
Challenge 2

Process design doesn't match floor reality

  • Wave strategies and pick paths assume ideal conditions that don't exist
  • Replenishment logic doesn't account for equipment constraints or labor availability
  • Exception workflows (shorts, damages, returns) aren't engineered
  • Slotting rules are theoretical and don't consider actual item velocity or handling
  • Receiving and putaway processes don't align to dock schedules and inbound variability
Symptom
"We're working around the system, not with it."
Challenge 3

Integrations work technically but fail operationally

  • ERP-WMS order sync doesn't handle cancellations, edits, or partials cleanly
  • Inventory status definitions differ between systems, creating trust issues
  • ASN and shipping integrations don't support carrier compliance rules
  • EDI mappings don't reflect how retailers actually want to receive data
  • Automation interfaces (WCS, conveyors, AS/RS) aren't tested under real volume
Symptom
"Orders get stuck between systems and nobody owns it."
Challenge 4

Inventory accuracy isn't achieved before go-live

  • Cycle counting discipline doesn't exist, so accuracy degrades immediately
  • Physical inventory is rushed and incomplete, seeding bad data into the new WMS
  • Location verification isn't enforced, so product ends up in unmapped places
  • Receiving discrepancies aren't resolved before putaway, compounding errors
  • WIP and in-transit inventory aren't accounted for during cutover
Symptom
"We're live, but we don't trust what the system says we have."
Challenge 5

Testing proves screens, not workflows

  • UAT scenarios are scripted and clean, missing the chaos of real operations
  • Volume testing doesn't happen, so wave timing and labor capacity are untested
  • Exception handling (shorts, subs, damages, returns) isn't validated
  • Automation and RF device performance under load is assumed, not proven
  • Integration failure modes and retry logic aren't rehearsed
Symptom
"It worked in testing, but the floor is overwhelmed."
Challenge 6

Cutover is under-planned and over-optimistic

  • Open orders and in-process work aren't governed, creating inventory limbo
  • Day 1 rules (what freezes, what moves, who escalates) aren't clear
  • Dress rehearsals don't happen, so nobody knows what Day 1 actually looks like
  • Rollback plan doesn't exist or isn't realistic given the data conversion
  • Parallel operations are attempted without clear reconciliation rules
Symptom
"We went live, but we don't know what's real."

Post Go-Live Utilization Issues

Why WMS Adoption and Performance Degrade

Utilization Issue 1

Users work around the system instead of with it

  • Supervisors override picks and replenishment because they don't trust the logic
  • Exception processes require manual workarounds that weren't designed
  • Tribal knowledge fills gaps where the system should be guiding behavior
  • Training was generic and didn't cover how to handle real floor scenarios
Symptom
"We're slower than we were before, and nobody knows why."
Utilization Issue 2

Reports and dashboards don't match operational needs

  • KPIs are system-generated but not operationally meaningful
  • Real-time visibility is promised but not delivered, so teams fall back to spreadsheets
  • Exception management requires manual queries instead of proactive alerts
  • Executive reporting doesn't align to the questions leadership actually asks
Symptom
"We have a WMS but we're still running the business in Excel."
Utilization Issue 3

Advanced features are configured but not used

  • Slotting optimization is turned on but never maintained
  • Labor management exists but isn't trusted or enforced
  • Wave planning features are ignored because manual control feels safer
  • Automation features degrade because exception handling wasn't engineered
Symptom
"We paid for features we'll never actually use."
Data Conversion and Migration

Where Data Migration Breaks

Data Pitfall 1

Legacy data is migrated as-is without cleansing

  • Duplicate items, obsolete SKUs, and inactive locations come over unchecked
  • UOM conversions are assumed to be correct but aren't validated
  • Item attributes are incomplete or inconsistent across the dataset
  • Location hierarchies and zones don't map cleanly to the new structure
Symptom
"The new system is just as messy as the old one."
Data Pitfall 2

Inventory conversion is rushed and inaccurate

  • Physical counts happen too far in advance of go-live, so drift occurs
  • Lot, serial, and expiration data aren't captured or validated
  • WIP and in-transit inventory are lost or double-counted during cutover
  • Location assignments in the new WMS don't reflect physical reality
Symptom
"We're finding product in places the system doesn't know about."
Data Pitfall 3

Open transactions and work-in-process aren't governed

  • Open orders in the old system create confusion about what to ship from where
  • Partially completed picks and putaways are lost during the transition
  • Returns and RTV workflows in flight have no clear path forward
  • Cycle count and adjustment transactions aren't reconciled before cutover
Symptom
"Orders are stuck between the old and new system."

Legacy System Sunset and Replacement

The Challenge of Replacing an Existing WMS

Replacing a WMS is harder than implementing a new one. The legacy system holds operational history, user muscle memory, workarounds that have become process, and integrations that nobody fully understands anymore.

Cutover isn't just technical. It's operational continuity under uncertainty.

Replacement Challenge 1

Legacy system holds undocumented processes and integrations

  • Customizations and workarounds are embedded but not mapped
  • Integration touchpoints are discovered late, creating go-live risk
  • Reports and queries that operations depends on aren't replicated
  • Exception handling that "just works" in legacy isn't designed in the new WMS
Replacement Challenge 2

Parallel operations are attempted without clear rules

  • Both systems run simultaneously but reconciliation doesn't happen
  • Users default to the old system because it's familiar and trusted
  • Inventory becomes fragmented across systems with no single source of truth
  • Cutover decision criteria aren't defined, so teams stay in limbo
Replacement Challenge 3

Decommissioning is rushed or incomplete

  • Historical data and audit trail access aren't preserved properly
  • Legacy reports are turned off before replacements are validated
  • Users still need legacy for edge cases but access is cut prematurely
  • Vendor support and licensing end before operational dependency does
What Good Looks Like

Measurable Success in WMS Programs

  • Inventory accuracy stabilizes above 98% within 30 days
  • Pick and ship productivity returns to baseline within 2 weeks
  • Exception volume decreases as workflows mature
  • Users trust the system and stop working around it
  • Integrations run reliably without manual intervention
  • Reporting becomes proactive, not reactive
  • Slotting and replenishment logic is maintained, not overridden
  • Advanced features (labor management, wave optimization) are actually used
  • Training is continuous, not just a one-time event
  • Legacy system is decommissioned cleanly with audit trail intact
  • Data quality improves over time instead of degrading
  • Operations becomes data-driven, not anecdote-driven
