Change Management Is the Most Underfunded Part of Every SAP Migration

Change Management Is the Most Underfunded Part of Every SAP Migration

Every study of ERP failure points to the same pattern: technology gets the budget, and the people who have to run the new system every day get what's left over. With SAP's 2027 support deadline compressing timelines across the industry, that imbalance is getting harder to absorb, even with AI tools helping stretch the training budget a bit further.

SAP's mainstream maintenance for ECC ends December 31, 2027, and the pressure that date creates isn't limited to SAP itself. As the installed base moves toward S/4HANA, the pool of consultants, systems integrators, and third-party support providers still fluent in ECC-era configuration is thinning out too, a predictable pattern whenever a platform generation winds down. Organizations weighing when to move are increasingly weighing it against a shrinking bench of people who can still support the old system well.

That deadline pressure tends to pull attention toward the technical workstream: data conversion, custom code remediation, testing, cutover sequencing. What it doesn't pull attention toward, consistently, is the several thousand employees who will have to do their jobs differently the day the new system goes live. This piece looks at why organizations chronically underfund the human side of ERP transformation relative to the technical side, and what that gap costs once the deadline arrives. AI-assisted training tools get one mention near the end, as a way to stretch an already thin change-management budget a little further, not as the fix for the underlying funding problem.

Prosci's 2025 research on ERP implementations quantifies a pattern that shows up across virtually every large transformation. Organizations spend an average of 92% of ERP budgets on technology and roughly 8% on change management. Yet the same organizations' leaders, asked in hindsight what
