The question asks to identify correct success factors for specific dimensions of a change management framework, which in the context of SAP S/4HANA, aligns with the SAP Activate methodology's Organizational Change Management (OCM) workstream.

A. A compelling change story is a cornerstone of the Change Communication dimension. It articulates the "why" behind the transformation, creating a shared understanding and vision, which is critical for gaining buy-in from stakeholders.

B. Measuring Change Effectiveness is crucial for understanding adoption and realizing benefits. A balanced set of measures (e.g., system usage statistics, user proficiency assessments, business KPI improvements) provides a holistic view of the change's success.

C. Change Realization is about achieving the intended business value. A new operating model (including processes, roles, and structures) is often the vehicle for this value. Therefore, actively supporting its development and adoption is a direct and critical success factor for realizing the project's benefits.

D. This option incorrectly conflates two distinct OCM dimensions. Change Leadership focuses on securing active sponsorship, while Stakeholder Management is a broader activity of engaging all affected groups.

E. This statement is a general goal for the entire OCM effort, not a specific success factor for the Change Strategy dimension. A success factor for the strategy itself is its alignment with business objectives.

The "Communication Plan" deliverable emphasizes developing key messages and a change story to drive engagement (supports A).

The "Business Adoption Measurement" deliverable outlines the need to define metrics to measure the success of the change (supports B).

The "Change Impact Analysis" deliverable focuses on identifying changes to business processes and roles, which are foundational to a new operating model and essential for benefit realization (supports C).

2. SAP Press Publication: In "Implementing SAP S/4HANA: A Framework for Planning and Execution" (ISBN: 978-1-4932-1483-9), the chapter on Organizational Change Management outlines key success factors.

Section 10.3.3, "Communication," discusses the necessity of creating a vision and a compelling change story.

Section 10.3.6, "Measuring Success," highlights the importance of defining and tracking KPIs to measure adoption and business value.

Section 10.3.2, "Change Impacts," describes analyzing process and organizational changes as a prerequisite for preparing the business and realizing the change.
