ERP implementation has a bad reputation in India — and most of it is deserved. Businesses buy software, get handed a set of credentials, and are left to figure out configuration, data migration, and training on their own. Six months later, the system is being used for half its intended purpose, and the operations team has rebuilt their Excel sheets. The software is not the problem. The implementation approach is.
Why Most ERP Implementations Fail
- No dedicated internal champion: the ERP is handed to IT, not owned by operations leadership
- Rushed go-live: management pressure to launch before the system is properly configured
- Incomplete data migration: opening balances, item masters, and vendor data are dirty or missing
- Insufficient training: admin staff are trained but daily users are not
- No post-go-live support: vendor disappears after sign-off, leaving the business to self-serve
The Aarcturus 3-Phase Implementation Model
- 1Phase 1 — Discovery (Week 1–2): Operational audit, process mapping, configuration design, data cleansing plan, training schedule
- 2Phase 2 — Execution (Week 3–5): System configuration, data migration, module-by-module training, parallel run with existing systems
- 3Phase 3 — Go-Live and Growth (Week 6+): Supervised go-live, daily support for the first 30 days, optimisation based on real usage data
Week-by-Week: What Actually Happens
| Week | Activity | Owner |
|---|---|---|
| Week 1 | Operational audit — map every business process to ERP module | Aarcturus architects + client leadership |
| Week 2 | Configuration design review, master data extraction from Tally/Excel | Both teams |
| Week 3 | System configured, item master and vendor master imported, initial training for admin users | Aarcturus + IT |
| Week 4 | Department-wise training — finance, procurement, warehouse, sales, HR | Aarcturus trainers + HODs |
| Week 5 | Parallel run — new system alongside existing, compare outputs, fix gaps | All users |
| Week 6 | Go-live — existing systems switched off, full operations on Aarcturus ERP | All teams |
Data Migration: The Make-or-Break Step
The most common implementation failure point is data migration. Every business has years of history in Tally, Excel, or a previous ERP — opening stock balances, customer ledgers, vendor payables, fixed assets. Migrating this data correctly requires extraction, cleaning, mapping, validation, and a final sign-off by the finance team before go-live. Aarcturus handles the full migration — you do not receive a template to fill in and figure out yourself.
Training: Who Needs to Learn What
Not every user needs to understand every module. Aarcturus delivers role-based training — the warehouse team learns receiving, dispatch, and inventory; the finance team learns AP, AR, and GST; the sales team learns CRM and order management. Everyone gets trained on their specific workflows, not a generic system tour. Training is repeated until every user can operate confidently without assistance.
What Post-Go-Live Support Looks Like
The first 30 days after go-live are the most critical. Real transactions surface edge cases that training scenarios never cover. Aarcturus stays on-call for daily support during this period — same-day response, not a ticket queue. After 30 days, usage data is reviewed to identify where the system is being under-used and where additional training or configuration can add value.
