An SAP cloud implementation is holistic because it affects multiple facets of the organization, not just isolated areas. Option C is correct as it encapsulates the four key dimensions of transformation: technology (new cloud systems), process (best-practice adoption), organization (structural adjustments), and people (behavioral change). This aligns with SAP’s view that cloud projects drive end-to-end change. Option A is too narrow—supplier/customer collaboration is just one potential impact. Option B is also limited; impacting employees and managers is part of the “people” dimension but doesn’t cover the full scope. Option D focuses only on IT, ignoring process, organization, and people changes. SAP OCM emphasizes a comprehensive approach to transformation, making C the definitive answer.

“SAP cloud implementations are holistic transformations, impacting technology, processes, organizational structures, and people, requiring a coordinated change management approach across all dimensions” (SAP Organizational Change Management Framework, Overview).
