What internal team do you need for an ERP implementation?

A successful ERP implementation needs a dedicated project manager, executive sponsor, department leads from finance, operations, and IT, and key power users from each functional area. For mid-market implementations, expect to commit 25-50% of a project manager's time and 10-20% of key department leads' time for 6-12 months. Underestimating internal resource needs is a top implementation failure cause.
