Which of the following approaches is NOT a part of RISE with SAP Journeys?

The approach of complete outsourcing is not considered a part of RISE with SAP Journeys. RISE with SAP is designed to facilitate organizations in their journey toward becoming intelligent enterprises by leveraging cloud solutions, process transformation, and industry best practices. The focus is on enabling companies to innovate and transform their SAP landscapes while enhancing their capabilities to respond to changing business needs.

On the other hand, the other approaches listed—Greenfield ERP Implementation, Multi-Step ERP Transformation, and Hybrid Two-Tier Approach—align well with RISE with SAP's objectives. Greenfield ERP Implementation focuses on establishing new SAP environments from scratch, allowing businesses the flexibility to adopt the latest technologies without legacy constraints. Multi-Step ERP Transformation emphasizes gradual change, enabling organizations to incrementally transition to new solutions while managing risk effectively. The Hybrid Two-Tier Approach provides flexibility in adopting cloud solutions alongside existing on-premise environments, catering to diverse business requirements.

Thus, complete outsourcing diverges from the RISE with SAP framework, which emphasizes active transformation and integration strategies rather than a hands-off outsourcing model.
