Companies facing ERP transition deadlines embrace step-by-step approaches to minimize disruptions, ISG Provider Lens^® report says

Many U.S. enterprises are dividing SAP transformation programs into manageable phases with milestones that demonstrate business outcomes, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2026 ISG Provider Lens^® SAP Ecosystem report for the U.S. finds that organizations are preparing for the end of mainstream SAP ECC support by carrying out controlled modernization strategies, often using AI, that balance transformation goals with operational continuity. Enterprises are sequencing programs into waves that each create incremental value, limiting the disruption of core processes. This approach reflects growing pressure from executive leadership to ensure accountability, cost discipline and measurable returns on large-scale technology investments.

“U.S. enterprises are no longer pursuing SAP transformation for its own sake but are aligning every step with measurable results,” Bill Huber, partner, ISG Digital Platforms and Solutions. “They are taking a disciplined approach that reduces risk while maintaining their momentum toward modern, AI-enabled ERP environments.”

As enterprises face the discontinuation of mainstream support for existing SAP ERP Central Component (ECC) systems in 2027, those in highly regulated sectors in the U.S. are accelerating migration to SAP S/4HANA to meet stringent compliance requirements. Those in less regulated industries, such as manufacturing, are more likely to defer migration decisions and consider buying extended support or third-party maintenance until 2030.

Companies are integrating new technologies into SAP environments to enhance system performance while retaining the ability to adapt to rapidly changing business conditions. AI adoption is expanding into production-level use cases to improve efficiency and reliability, including automated testing, incident resolution and system monitoring. Strategies are evolving toward standardized ERP cores supported by modern data and integration layers that enable flexibility and scalability. To simplify updates and maintenance, enterprises are reducing customization by building extensions outside the core environment using SAP Business Technology Platform.

U.S. companies with SAP are looking for clear choices among greenfield, brownfield and selective data transformation. Many large enterprises with complex environments are pursuing selective modernization instead of full system replacement due to heightened sensitivity to operational risk and the need for continuity. Meanwhile, SAP is targeting the midmarket for greenfield projects through the GROW with SAP program, ISG says.

“AI is central to SAP modernization for U.S. enterprises, but the need for operational resilience guides their strategies and execution,” said Tarun Nathooram Vaid, principal analyst at ISG and lead author of the report. “Service providers play a key role by supporting structured transitions and helping clients navigate the complexity of SAP transformations.”

The report also explores other trends affecting SAP adoption in the U.S., including growing demand for industry-specific accelerators and an increasing focus on data quality and integration as foundations for long-term transformation success.

The report evaluates the capabilities of 44 providers across five quadrants: SAP S/4HANA Transformation — Large Accounts, SAP S/4HANA Transformation — Midmarket, SAP Application Managed Services, SAP Business AI and Business Technology Platform (BTP) Services and Managed Cloud Services for SAP ERP.

Deloitte, EY, IBM and LTM are named as Leaders in three quadrants each, and DXC Technology and Tech Mahindra are named as Leaders in two quadrants each.

In addition, Atos, DXC Technology, Hitachi Digital Services, KaarTech, NTT DATA and Syntax are recognized as Rising Stars — companies with a “promising portfolio” and “high future potential” by ISG’s definition — in one quadrant each.

In the area of customer experience, Infosys is named the global ISG CX Star Performer for 2026 among SAP ecosystem providers. Infosys earned the highest customer satisfaction scores in ISG's Voice of the Customer survey, part of the ISG Star of Excellence™ program, the premier quality recognition for the technology and business services industry.
