Five case studies in successful RISE conversion.

Successful RISE with SAP conversion is the product of a small set of disciplined commercial, technical, and governance moves rather than the product of any single decision. The five case studies that follow describe anonymised conversion programmes across manufacturing, financial services, life sciences, retail, and the public sector. The case studies focus on the moves that made each outcome work, the trade offs that the buyer accepted, and the operating consequences that followed go live. The case studies are constructed from engagements completed in the prior twenty four months, with names and identifying detail removed.

Case one: a global automotive supplier

A tier one automotive supplier with operations across twenty two countries converted its legacy ECC estate to RISE with SAP S/4HANA Cloud Private Edition over a twenty two month programme. The initial RISE proposal from SAP was constructed at a five year term with full FUE conversion at standard ratios and a hyperscaler bundle priced through SAP. The buyer side response was a counter proposal that disaggregated the FUE conversion, reduced the user count by twenty eight percent against the SAP proposal through a disciplined user reclassification exercise, reset the hyperscaler arrangement to a direct contract with the hyperscaler outside the RISE bundle, and added a defined exit credit schedule that increased through the term.

The outcome was a forty one percent reduction in the seven year TCO against the original SAP proposal. The conversion programme delivered go live on the original target date with a hyper care period that closed within ninety days. The buyer accepted a slightly less integrated hyperscaler arrangement in exchange for the direct commercial relationship with the hyperscaler, which the buyer determined was the right trade off given the buyer view of long term operating costs.

Case two: a regional bank

A regional bank with assets of approximately ninety billion euros converted its SAP estate to RISE with SAP S/4HANA Cloud Private Edition under regulatory constraints that required data residency within the European Economic Area and operational controls that satisfied the relevant banking supervisor. The initial RISE proposal included a hyperscaler region selection that satisfied the residency requirement but did not satisfy the operational control requirement, and the standard service description did not include the supervisor mandated audit rights.

The buyer side response was a structured contractual addition that added the required audit rights, added the operational control covenants, added a defined exit assistance schedule with cost capped at a pre agreed maximum, and added a sub processor approval gate that gave the bank a defined approval right before any change to the sub processor list. The buyer accepted a small commercial premium in exchange for the contractual protections, which the bank legal and compliance functions assessed as necessary to satisfy the regulatory position.

The outcome was a successful conversion within the regulatory window. The operational controls satisfied the supervisor review at go live, and the audit rights have been exercised twice in the first year of operation. The bank operating risk position is meaningfully stronger than the standard RISE service description would have produced.

Case three: a life sciences manufacturer

A life sciences manufacturer with operations across three continents converted to RISE with SAP S/4HANA Cloud Private Edition with the additional constraint of GxP compliance for the validated systems within the SAP estate. The initial RISE proposal did not include the validation documentation, the change control discipline, or the audit support that the GxP compliance position requires.

The buyer side response was a structured addition that included a GxP compliance schedule, a change control protocol that aligned with the buyer quality system, a validation documentation deliverable for each release of the underlying platform, and a defined audit support obligation for regulatory inspections. The buyer accepted a defined incremental fee for the GxP service envelope in exchange for the compliance posture, which the quality and regulatory functions assessed as necessary to maintain the manufacturing license position.

The outcome was a successful conversion that maintained the GxP compliance position throughout the cutover and the first year of operation. The validated systems were re validated on the RISE platform under the buyer quality discipline, and no regulatory finding has surfaced against the SAP platform in the first eighteen months of operation.

Case four: a multinational retailer

A multinational retailer with operations across forty markets converted to RISE with SAP S/4HANA Cloud Private Edition with the additional complexity of seasonal capacity peaks that exceed average load by a factor of four. The initial RISE proposal sized the platform for the peak load, which produced a capacity envelope that was idle for ten months of the year. The buyer side commercial assessment found that the peak sizing was responsible for thirty two percent of the proposed TCO.

The buyer side response was a capacity model that combined a baseline RISE platform sized for the average load with a defined capacity flex envelope for the peak periods, priced separately and provisioned on demand. The capacity flex envelope was structured contractually with defined notice periods, defined cost units, and defined service levels that matched the operational requirement during the peak. The buyer accepted a slightly more complex capacity management process in exchange for the cost reduction across the non peak months.

The outcome was a forty seven percent reduction in the seven year TCO against the original SAP proposal. The capacity flex envelope has been exercised successfully through two seasonal peaks, with no service degradation during the peak windows.

Case five: a public sector agency

A central government agency converted its SAP estate to RISE with SAP S/4HANA Cloud Private Edition under public procurement rules that required transparent competition, defined evaluation criteria, and a contract structure that satisfied the public sector audit position. The initial RISE proposal was constructed within the standard SAP commercial framework, which did not align with the public procurement requirements in several material respects.

The buyer side response was a structured procurement process that ran the RISE conversion alongside a defined comparison with alternative options including a brownfield migration and a hybrid model. The procurement documented the comparative analysis under the public sector evaluation framework, which provided the audit position that the RISE outcome required. The procurement also added contractual protections specific to the public sector position, including a defined right to publish the contract under freedom of information rules and a defined service continuity obligation during any future supplier change.

The outcome was a successful conversion within the public procurement framework. The transparent procurement documentation has stood up to two subsequent audit reviews, and the contract structure has served as the template for two additional public sector RISE conversions in adjacent agencies.

Conclusion: the moves that recur across successful conversions

The five case studies vary in industry, scale, and constraint. The common elements across the five outcomes are a disaggregated commercial counter position that addresses each component of the RISE proposal independently, a contractual structure that adds the buyer specific protections that the standard service description does not include, a capacity model that aligns the platform sizing with the operating load rather than the peak load, and a governance discipline that maintains the buyer position through the cutover and the first ninety days of operation. The conversion outcome is the product of these moves applied consistently across the negotiation, the contract, and the implementation. A buyer that runs each move with discipline captures the outcome that the case studies describe. A buyer that runs the conversion as a procurement exercise rather than as a structured negotiation accepts the outcome that the standard RISE proposal produces.
