ERP Go-Live Checklist: 40 Steps Before You Launch Your Implementation

The go-live decision is the most consequential moment in an ERP project. Going live on a system that is not ready creates operational chaos that is significantly harder to reverse than delaying the launch. This checklist covers the 40 checks that most implementation teams rush, skip, or underemphasise.
