The first 90 days after ERP go-live should stabilise critical operations, prove financial and operational integrity, transfer ownership, and establish controlled improvement. It is not the moment to dissolve the project team or accept every enhancement request.
Days 0–14: Protect Operations
Run a command centre with business, functional, technical, data, integration, security, vendor, and support leads. Publish severity, triage, escalation, communication, and decision rules.
Monitor critical journeys, interfaces, batch jobs, access, queue failures, data quality, inventory, cash, order fulfilment, and support demand. Reconcile financial and operational control totals daily where risk warrants it.
Prioritise safety, compliance, revenue, customer, and close blockers. Keep temporary workarounds owned, documented, time-limited, and reconciled.
Days 15–30: Establish Control
Analyse defect patterns rather than treating every ticket independently. Separate configuration or data defects from learning, role, process, capacity, and integration issues.
Complete access and segregation reviews, backup and restore evidence, operational runbooks, monitoring, vendor escalation, and unresolved migration exceptions. Verify that audit trails and approvals work in real transactions.
Begin closing the first operational period early. Rehearse month-end activities and compare subledgers, ledger, inventory, receivables, payables, tax, and management reporting.
Days 31–60: Improve Adoption
Target coaching by role and observed error. Update procedures and knowledge articles. Measure process completion, cycle time, first-time-right rate, manual adjustment, workaround, and user confidence.
Identify shadow spreadsheets and off-system approvals. Decide whether each signals missing capability, poor training, an exceptional business need, or resistance to standard process.
Days 61–90: Transfer and Optimise
Move ownership to permanent product, platform, process, data, security, and support roles. Confirm service levels, release cadence, change approval, regression testing, environment management, and vendor governance.
Prioritise enhancements by business value, risk, effort, architecture, and adoption—not requester seniority. Protect the core from uncontrolled customisation.
Use Exit Criteria
End hypercare only when critical defects are controlled, reconciliations meet tolerance, support volume is sustainable, integrations are stable, owners accept runbooks, access is reviewed, recovery is tested, and remaining risk is explicitly accepted.
Publish a 90-day outcome review against the pre-implementation baseline. Carry unfinished actions into governed backlogs with funding and dates.
DualByte's ERP solutions service can lead go-live assurance, hypercare, reconciliation, and transfer to sustainable operations.
