ERP Implementation Experience Sharing
Practical Experience of ERP System Migration in a Button Factory
In the eyes of many enterprises, introducing an ERP system is a risky transformation. As long as it is planned properly and executed thoroughly, ERP can become an opportunity for an enterprise to be reborn. This article shares a real case of a traditional button factory successfully migrating from an old system to a new ERP system. The project took several months in total. Although the process was difficult, it eventually went live smoothly, laying a solid foundation for the enterprise's digital transformation.
Phase 1: Coding and Process Review
After the project started, the first task was to formulate coding rules for materials, semi-finished products, and finished products. This is a seemingly boring but crucial task. Because the old system's coding rules were chaotic, many materials had duplicate codes or multiple codes for one item. The project team spent up to 3 months to inventory and recode one by one, ensuring that every material, semi-finished product, and finished product had a unique and meaningful identifier. This laid the foundation for subsequent data import and inventory management.
After coding was completed, the team began meeting with each department one by one to review existing processes and discuss how the new system would operate:
* Product Technology Department (PTO): Discussed product design processes and production process preparation, and confirmed the document format of process routings.
* Production and Material Control Department (PMC): Discussed procurement and material control processes, and confirmed the formats of purchase orders, production orders, work orders, material issue notes, material return notes, and return-to-warehouse notes.
* Warehouse Department: Discussed receiving, incoming inspection, assembly, packaging, product quality inspection, and shipping processes, and confirmed the formats of receiving notes, inspection notes, assembly work orders, packaging work orders, transfer notes, adjustment notes, and shipping notes.
* Workshops (Cutting, Injection, Stamping, Die-casting): Discussed daily operations and production reporting methods, and confirmed the work order format for each workshop.
* Finance Department: Discussed invoicing, receipt, payment processes, and financial reports, and confirmed the formats of invoices, receipts, payment vouchers, accounts receivable, accounts payable, and financial statements.
Through these meetings, the team not only clarified the needs of each department but also allowed department heads to understand in advance the changes the new system would bring.
Phase 2: Data Preparation and Training
After processes were confirmed, the team prepared Excel import templates required by each department. These templates included item master data, supplier data, customer data, BOM, historical inventory, etc. Each department had to fill in and carefully check these Excel files to ensure data accuracy. At the same time, the team arranged system operation training for each department to familiarize employees with the new system's interface and operation methods. During training, employees raised many practical questions, and the team answered them one by one and compiled common questions into operation guides for each department.
Phase 3: Data Import and Problem Resolution
After preparation was ready, the team began importing basic data into the ERP system. At this stage, a small incident occurred: after the warehouse department imported data, they found errors in the Excel file, resulting in incorrect inventory data being imported. Facing this problem, the team did not panic but decisively deleted all imported data from the warehouse department, reorganized the Excel file, and re-imported it. The team spent 3 days repairing the data to ensure accuracy. It is better to spend more time checking data than to let erroneous data flow into the system.
Phase 4: Data Verification and Go-Live
After data import was completed, the team checked one by one whether the imported data was consistent with the old system. Including inventory quantities, customer balances, supplier data, etc., all had to match the old system's reports. After confirmation, the new system officially went live, and the old system was switched to backup status. ERP go-live is not the end. Because item coding had changed, during the early transition period, departments still encountered operational problems and needed time to get used to the new coding method and system interface. At the same time, technology continues to innovate, and the enterprise's operating environment will change over time. Continuous improvement and optimization are still needed in the future so that ERP can continue to create value for the enterprise.
Conclusion
This button factory case tells us that the key to successful ERP migration lies in: adequate coding and process review in advance, cross-departmental communication and collaboration, rigorous data preparation and checking, and a decisive attitude to correct errors when they occur. Although the process required 3 days to re-import due to Excel errors, it was this persistence in data accuracy that allowed the new system to run stably after go-live and bring real management benefits to the enterprise. For enterprises preparing to introduce ERP, this case is undoubtedly a highly valuable practical experience.
