ERP rollout critical path

This critical path diagram maps the decisions and dependencies in a compact ERP rollout. Scope confirmation releases configuration and data cleaning. Configuration supports both user training and migration testing, while data cleaning is also required before the migration test. Go-live waits for training and the tested migration path. The network helps a delivery lead distinguish activities that can overlap from the dependencies that cannot move. Adapt it for integration testing, cutover rehearsal, support readiness and approval gates in a real implementation.

ERP rollout critical path

Drawing preview

The request

“Create a critical path diagram for an ERP rollout: confirm scope, configure the ERP, clean data, train users, test migration, then go live.”

Then tryAdd a two-day security review before go-live.Change data cleaning to take eight days.

What is in this drawing

Read the decisions behind it.

01Scope gate

Configuration and data work start after scope.

02Readiness paths

Training and migration testing converge.

03Go-live gate

Both readiness paths must finish.

Use for a concise enterprise-system rollout.

FAQ

Common questions

Why test migration?

It verifies configuration and cleaned data before go-live.

Can training overlap data cleaning?

Yes, after configuration is complete.

What delays go-live?

Training or migration testing delays.
