Planning an ERP Go-Live? Avoid These 5 Costly Mistakes

ERP implementations — especially Oracle SCM — can unlock massive value. But too often, avoidable mistakes cause project delays, cost overruns, and frustrated teams.

Here are five costly mistakes we’ve seen over and over — and how to make sure your project stays on track.

1. Rushing Into Implementation Without Clear Requirements

Too many teams jump straight into design or configuration without crystal-clear business requirements. This leads to endless rework and scope changes.

Avoid it by:

  • Hosting detailed requirement-gathering workshops

  • Prioritizing critical business processes

  • Locking scope before design begins

2. Ignoring Master Data Quality Until the End

Bad data = bad decisions. If your item masters, suppliers, customers, or locations aren't clean, expect major issues during testing and go-live.

Avoid it by:

  • Starting data cleanup in parallel with the design phase

  • Assigning ownership for each data domain

  • Validating data early during mock cycles

3. Underestimating User Training and UAT

Even the best-configured system can fail if end-users aren't trained or confident. Often, testing and training are rushed to meet deadlines.

Avoid it by:

  • Creating role-based training plans

  • Involving business users early in UAT

  • Running mock sessions and feedback loops

4. Over-Customizing the System

Trying to replicate legacy systems inside Oracle? That’s a fast lane to delays. Customizations should be exceptions, not the rule.

Avoid it by:

  • Leveraging Oracle Cloud’s best practices

  • Limiting extensions to business-critical needs

  • Reviewing all customizations with business and IT stakeholders

5. Not Having a Realistic Cutover Plan

Go-live is not just a date — it’s a process. Teams often underestimate the complexity of cutover tasks like inventory snapshots, open orders, and interfaces.

Avoid it by:

  • Building a detailed, task-driven cutover plan

  • Assigning clear ownership for every activity

  • Running a dry run 2–3 weeks before the actual go-live
