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.

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. 7 min read | Orpington Technologies Insights 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. The Investment Gap That Keeps Repeating 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 Page 1 of 4

Prosci's research goes further and puts a number on the gap: human factors matter roughly six times more than technical factors in determining whether an ERP program actually realizes its intended benefits. That gap isn't a training-budget footnote. It's a structural mismatch between where the risk actually sits and where the money goes. And it's a big part of why so many technically successful go-lives (the system works, the data migrated, the integrations hold) still fail to deliver the productivity and adoption the business case assumed. Stretching a Chronically Thin Budget Further Traditional ERP training follows a fixed sequence: classroom or e-learning sessions before go-live, a set of static job aids, and a help desk queue after go-live for whatever the training didn't cover. When the change management budget is already a fraction of what the technology workstream gets, that sequence tends to get compressed further under deadline pressure, and the compression usually falls on the parts hardest to see from a project plan: refresher sessions, role-specific job aids, and contextual support during the weeks after cutover, when the change is heaviest. Employees who get one training pass weeks before go-live often meet the actual system for the first time on the day they're expected to be productive in it. Some organizations are using AI copilots and in-app assistants, including SAP's Joule and comparable tools, to put a fraction of that support back without adding headcount, answering routine how-do-I questions in the moment instead of routing them to a training team or help desk that's already stretched thin. It's a genuine efficiency gain and a reasonable way to make a thin training budget cover more ground. It doesn't change the underlying math, though. A program that starts from a change-management allocation in the single digits is still starting from that allocation, whatever tools it deploys inside it. Page 2 of 4
Orpington Technologies | SAP S/4HANA Migration Insights © Orpington Technologies Inc. www.orpingtontech.com Why Adoption Rate Itself Is the Real Lever The more interesting number in SAVIC's research isn't the deflection rate. It's what adoption intensity does to measured productivity. Deployments reaching 60% or higher weekly-active adoption produced three to four times the measured productivity improvement of low-adoption deployments using the same underlying tools. The AI copilot itself doesn't generate that value. Getting enough of the workforce to actually use it, consistently, does. And that puts change management back at the center of the picture instead of the periphery. SAVIC's research also offers a specific, actionable number here: high-performing implementations allocate 15–25% of their total AI programme budget specifically to change management, nearly double the average share Prosci found across ERP programs generally. There's a reason for that. It's the closest thing in this research to a direct causal link between change management investment and realized value from AI-assisted tooling. 3–4x the productivity improvement seen in deployments with 60%+ weekly-active adoption, compared to low-adoption deployments using identical AI tooling. (SAVIC Technologies, citing SAP data) The Risk Worth Naming An always-available AI copilot can quietly become a crutch instead of a bridge to real capability, if it's the only investment a program makes in adoption. A user who can always ask a chatbot how to complete a transaction may never build the underlying process fluency the organization needs, particularly for less routine scenarios the copilot hasn't seen enough of to answer well. The programs getting this right use AI copilots to absorb the high-volume, routine question load. That frees a genuinely well-resourced change management team (trainers, champions, super-users) to focus on the harder work: building real capability and handling process changes that need more than a quick answer.

Orpington Technologies | SAP S/4HANA Migration Insights © Orpington Technologies Inc. www.orpingtontech.com Where This Leaves You Change management is one of the areas Orpington Technologies pushes hardest on, both in the programs it leads directly and in the independent diagnostics it runs for clients weighing their own migration timeline. With the ECC support window closing at the end of 2027 and the pool of specialists who know that platform well shrinking alongside it, waiting to fix the training gap until closer to go-live only compresses an already tight schedule. Orpington's migration practice pairs deep SAP technical delivery with a change management function built to actual scale rather than bolted on near cutover, using AI-assisted tooling as one of several ways to make that investment go further.
