While external partners are indispensable for technical execution, they often lack the granular business context required to navigate complex ERP transformations. According to Info-Tech research analyst Mia Scherba, companies rarely perform these migrations often enough to build internal expertise, yet they must retain control over priorities and acceptable trade-offs. Relying on vendors to set the strategic direction can lead to an underestimation of technical complexity, especially when teams treat the transition as a simple upgrade rather than a holistic business evolution.

To mitigate these risks, Info-Tech advocates for a three-phase planning methodology that firms should complete before engaging external technical help. This framework involves auditing the current SAP landscape, defining clear deployment strategies, and formalizing governance structures. By establishing these internal guardrails, organizations ensure that implementation partners execute against a predefined roadmap rather than steering the business into unintended constraints. Ultimately, the success of an S/4HANA migration depends on internal ownership of decisions regarding organizational readiness and user adoption, which remain beyond the scope of a technical partner's mandate.
