ERP Post-Go-live: The Beginning or a Money Pit?
Many businesses mistake Go-live for the finish line. In reality, that's when the real battle for system integrity begins. Insights from 20 years in the trenches.
I am Nguyen Manh Tuong.
After 20 years of implementing ERP, SCM, and HRM systems across various industries, I’ve seen a recurring tragedy: 80% of enterprises fail not before Go-live, but 6 months after.
CEOs often celebrate the launch and then hand the keys to the IT department, thinking the job is done. This is a fatal mistake. An ERP system without proper maintenance and upgrades is like a vacant real estate property—it depreciates rapidly and becomes a liability rather than a high-yield asset.
1. The “Mission Accomplished” Illusion
In the Vietnamese market, especially for firms transitioning to VAS (Vietnam Accounting Standards), the biggest hurdle isn’t the tech—it’s the habit. Post-Go-live, under operational pressure, staff often retreat to Excel for “speed.”
“ERP is not software you buy and install. It is a management discipline you practice every single day.”
If you don’t enforce data integrity immediately after Go-live, your system will quickly turn into a data graveyard.
2. Maintenance vs. Optimization: Know the Difference
Don’t confuse bug fixing with Optimization. Look at how a strategic leader views these two functions:
| Feature | System Maintenance | System Optimization/Upgrade |
|---|---|---|
| Objective | Keep the system alive. | Make the business run faster. |
| Frequency | Daily / Hourly. | Quarterly or per business cycle. |
| Execution | Internal IT / Vendor Support. | Consultants & Key Users. |
| Outcome | Stability. | Competitive Advantage. |
| Financial Logic | Operating Expense (OPEX). | Strategic Investment (CAPEX). |
3. Inside Info: The Over-Customization Trap
I once consulted for a large distribution firm that demanded heavy Customization of their DMS and ERP to satisfy old employee habits. The result? When the software vendor released a new version with advanced features, they couldn’t upgrade due to source code conflicts.
My advice: Keep the Core clean. If you want to upgrade the system post-Go-live, upgrade your people’s mindset first.
4. Risk Management and System Finance
Applying my current focus on Personal Finance and Real Estate, I view an ERP as an investment portfolio:
- Risk Management: Do you have a contingency plan when the system freezes on the last day of the month?
- ROI: One year after Go-live, by what percentage has your inventory cost decreased? How much has your capital turnover improved?
If you cannot answer with hard data, your system is on life support.
Final Thought: Don’t let your ERP become an expensive monument. Make it a living entity, constantly nourished with clean data and sharpened by decisive management.
Day 88. The journey continues.
