Introduction: Go-Live Is Only the Beginning
Implementing a warehouse management system is more than configuring software and switching it on. In a complex manufacturing environment, success depends on coordinating IT infrastructure, validating data, preparing users across multiple shifts, resolving real-world operational issues, and helping the customer become confident running the system independently.
For one large manufacturing facility in Mexico, the implementation of Codeworks Enterprise WMS across two production lines put those challenges into sharp focus.
The project involved a weekend ERP cutover, a multilingual workforce, last-minute network and printer readiness, and a warehouse team learning new system-directed processes while keeping production operations moving.
Over the following 90 days, the focus evolved from intensive on-site support to troubleshooting, process stabilization, and greater customer independence. This is what happened and what the experience reveals about implementing a WMS successfully.
The Starting Point: An Implementation with Real Operational Stakes
The facility was the largest operation in its corporate group at the time, with the largest plant footprint, warehouse footprint, and headcount. It operated across three shifts, typically supporting approximately 80 units of daily production, with peaks of 130-140.
The WMS implementation covered two production lines and included receiving, inventory management, kitting, piece picking, standard packing, load-out, and manifest transactions integrated with the customer's existing ERP system.
The scale of the environment made coordination essential. Approximately 5,000-7,000 SKUs were active in day-to-day operations, drawn from a much larger item master of roughly 350,000 items.
The customer was not starting from scratch with the software. Codeworks Enterprise was already operating in two other facilities within its organization. The project extended a proven system and established an operating approach to another large facility.
That familiarity reduced the uncertainty associated with adopting an entirely new platform, but it did not eliminate the work required to make the implementation successful at this site.
The challenges before go-live
Several dependencies needed to be resolved before the new system could support live operations:
- ERP transition: The existing ERP warehouse structure needed to be converted to a non-located warehouse, so Codeworks Enterprise could manage inventory locations.
- Network and printer connectivity: Network configuration and firewall changes were required to enable communication between the WMS server and physical printers.
- Data alignment: Item records, order quantity multipliers, standard pack quantities, and supplier information needed to match between the ERP and WMS.
- Training across three shifts: Users needed practical training on the new workflows, with additional sessions required for second- and third-shift employees.
- Cross-team coordination: Plant logistics, ERP support, IT, network teams, and the project manager had to work together around a fixed cutover window.
- Language and communication: Training and support had to accommodate both English and Spanish-speaking users.
These were not simply technical checklist items. Each dependency affected the team's ability to train users, validate workflows, and begin processing transactions reliably.
Days 1-30: Discovery, Cutover, and the Reality of Go-Live
The first 30 days were about moving from implementation planning to live operation, resolving early issues, and helping users build confidence in the new system.
Preparation had started well before go-live. During the previous few months, the plant shared operational information to support training and standard-work planning. It also arranged a visit to another facility already using Codeworks Enterprise, giving its team an opportunity to see the system in operation before deployment.
As the project approached cutover, attention shifted to technical readiness and the coordination of multiple teams.
The final days before launch
A critical network and printer connectivity issue remained close to the deadline. Although the firewall had been updated earlier in the month of go-live, the customer's IT team completed the necessary network corrections just three days before go-live.
The ERP transition presented another major dependency. Converting the existing warehouse configuration took approximately 15 hours. The plant needed to complete and verify that conversion before handing over the data for the WMS upload.
The sequence was fixed:
- 2 Days Before Go-Live: ERP cutover.
- 1 Day Before Go-Live: WMS data load.
- Day of Go-Live: Go-live across the two production lines.
With multiple teams working against the same deadline, the cutover required careful sequencing, clear responsibilities, and close coordination.
Day 1: The warehouse becomes the test environment
Two Codeworks consultants were on site for the first 2 weeks, providing coverage across day and night operations.
Approximately 40-50 users were involved at go-live across receiving, picking, shipping, and other warehouse processes. All shifts went live on Day 1.
Monday was chaotic. The implementation team moved constantly around the facility, answering questions and troubleshooting issues as users encountered new workflows in live operations.
Some issues exposed the importance of process discipline and accurate master data.
For example, kitting depended on inventory movements being recorded in WMS. If material was physically moved to the kitting area without the corresponding system transaction, the system could show the kit cell as short. Training reinforced the importance of recording each movement.
The team also corrected item records where ERP and WMS values did not align, including order multipliers, standard pack quantities, and supplier information.
From firefighting to routine operations
The first week showed clear progression.
- Monday: Intensive troubleshooting and frequent user questions.
- Tuesday: Users began becoming familiar with Codeworks Enterprise WMS, and the immediate disruption eased.
- Wednesday: Operations became noticeably calmer.
- Thursday and Friday: Processing was approaching normal, with support increasingly focused on frontline supervisors.
The implementation team did not simply monitor the system remotely. Its presence across both shifts allowed issues to be addressed where the work happened, with direct observation of user behavior and actual operating conditions.
After the on-site weeks, follow-up calls continued to review issues such as manifests sent from the WMS versus transactions loaded into the ERP. The final recorded post-implementation follow-up call took place 3 weeks after go-live.
The lesson from the first 30 days: A successful go-live is not defined by whether the system is switched on. It is defined by how quickly the operation can work through real issues and establish reliable daily processes.
Days 31-60: Stabilization, Corrections, and Growing Ownership
Once the initial launch period had passed, the emphasis shifted from intensive floor support to resolving outstanding issues, improving user understanding, and helping the customer manage more situations independently.
This phase also showed why implementation work continues long after the first transactions have been processed.
Resolving the issues that surface in live operations
During this period, the team and customer addressed a range of practical operational questions:
- Open and cancelled advance shipping notices (ASNs): The plant agreed to a two-week expiry period for open ASNs and requested reporting on cancelled records.
- Stuck requisitions: The plant cleared older requisitions for one production line, resolving nearly all of them without external intervention.
- Rack-sheet progression: The plant confirmed rack sheets through a specified point, while the next sheet remained on hold because of a material shortage.
- Inventory record recovery: Two months after go-live, a user deleted a license plate rather than transferring it. Codeworks reversed the error, prompting a discussion about which corrections users could perform themselves.
- Future expansion: By the end of the second month, the plant was discussing the next warehouse area, including dock zones and dedicated production-line locations.
These examples illustrate an important distinction: not every issue encountered after go-live is a software defect. Some involve data, material availability, user decisions, or the way a process has been defined. Effective implementation support means identifying the cause and determining the appropriate response.
Moving beyond dependency on the implementation team
As users gained experience, they began handling more routine situations without needing the implementation team to intervene.
The license-plate incident highlighted an opportunity to improve that independence. The team corrected the immediate problem, while the customer's question exposed a broader need: users needed to understand which errors they could resolve themselves and when escalation was necessary.
At the same time, the customer was already considering how to extend the WMS into another warehouse area. Expansion discussions began while the original implementation was still being stabilized.
That is an important milestone in a WMS project. The customer is no longer focused exclusively on getting the initial scope working; it is beginning to consider how to apply the system more broadly.
The lesson from days 31-60: Stabilization is about more than closing tickets. It is about building the knowledge, procedures, and confidence required to manage the operation day to day.
Days 61-90: From Implementation Support to Operational Self-Sufficiency
By the final month of the 90-day period, the focus had shifted further toward customer independence, reporting, and preparation for the next phase.
The project's email history provides one useful (but imperfect) indicator of this progression. Weekly email volume decreased by 82% compared with substantially higher volumes during the early stabilization period.
Email volume alone cannot establish operational performance, and later increases coincided with planning for the next phase and onboarding additional users. Nevertheless, the records illustrate how the nature of implementation support evolved over time.
A meaningful sign of adoption
One of the clearest examples came in the third month, when a plant user thanked Codeworks for teaching him how to correct a license-plate location problem and said he would practice the procedure.
It was a small interaction, but an important one.
The implementation team had moved beyond correcting a specific issue. It helped a user understand how to handle that type of situation independently.
Other activities during this period included preparing Excel exports of line-set reports so the plant could compare them against ERP data and scheduling a kickoff meeting to discuss go-live for the next phase and expansion.
By Day 90, the original scope remained the focus of stabilization. No additional reports, processes, or warehouse areas had been added to that scope during the period.
The operational milestone was not a dramatic new feature release. It was that users were becoming self-sufficient, supervisors were managing their operations and answering team questions, and routine support was no longer dependent on the implementation team being physically present.
The lesson from days 61-90: The real measure of implementation maturity is whether the customer can operate, resolve routine issues, and support its users without relying on the project team for every answer.
Five Lessons from the First 90 Days
1. Infrastructure readiness must be verified early
Printer and network connectivity remained a concern until the final days before go-live. Late resolution put pressure on training and cutover preparation.
What to take away: Validate network paths, firewall rules, printers, scanners, and other hardware in the actual operating environment well before the launch window.
2. Master data needs operational validation, not just a successful load
Differences in order multipliers, pack quantities, supplier information, and inventory movements affected live workflows.
What to take away: Test representative transactions against real operating rules. Confirm that item, location, inventory, and order data support the processes users must execute.
3. Training must reflect the actual workforce
Training across three shifts, in English and Spanish, created practical constraints. Additional sessions were needed, and scanner software changes shortly before launch added complexity.
What to take away: Plan role-based, shift-specific training early. Use the actual hardware and workflows where possible, and ensure employees can perform their jobs rather than simply navigate the software.
4. Go-live issues reveal gaps in process understanding
The IKS request-feed problem, missing movement transactions, and incorrect license-plate handling showed that real operations expose issues that may not appear during demonstrations.
What to take away: Test exception scenarios, reinforce critical transactions, and establish clear procedures for correcting errors and escalating issues.
5. Post-go-live support should build independence
The progression from intensive floor support to users resolving problems themselves was one of the most meaningful outcomes of the 90-day period.
What to take away: Plan for a structured transition from hands-on implementation support to supervisor ownership, user self-service, and ongoing operational improvement.
What We'd Tell a Company Starting a WMS Implementation Tomorrow
The experience reinforced several practical recommendations for organizations preparing to implement a warehouse management system.
- Start validating master data and operational rules earlier than you think you need to.
- Confirm network, printer, scanner, and hardware readiness before the final week.
- Involve warehouse users and supervisors in process design and testing.
- Plan training around actual roles, shifts, languages, and equipment.
- Test exceptions and recovery procedures, not just ideal transactions.
- Coordinate ERP, IT, network, warehouse, and implementation responsibilities around a clearly defined cutover plan.
- Budget for intensive support immediately after go-live.
- Define what operational independence should look like at 30, 60, and 90 days.
Most importantly, do not treat go-live as the finish line.
The system must become part of how the warehouse operates. That takes time, practical problem-solving, reinforcement, and a deliberate transfer of knowledge to the people who will run it.
The Outcome: A More Self-Sufficient Operation
At the end of the 90-day period, the implementation had progressed from a high-intensity launch to a more self-sufficient operating environment.
The original two-line scope had been stabilized; users were increasingly capable of handling routine questions, and supervisors were supporting their teams without relying on Codeworks for every issue. Meanwhile, the customer had begun planning for a subsequent phase.
The project also demonstrated that successful implementation depends on much more than the software itself. Infrastructure, data quality, process discipline, training, cross-team coordination, and responsive post-go-live support all shaped the transition.
For organizations considering a WMS implementation, the takeaway is straightforward: the first 90 days are not simply a period to wait for the system to settle down. They are a structured opportunity to turn a configured solution into an operational capability.
Go-live starts the transition. Stabilization builds confidence. Knowledge transfer creates independence.
