The Definitive Guide to SAP Go Live is a 650‑page reference work on cutover governance. Far beyond theory, it delivers a ready‑to‑use governance system for the most critical phase of digital transformation. At its core is the Cutover Governance Matrix (CoGM), a structured framework for planning, execution, and audit.

These tools provide project leaders with a decisive time advantage, enabling them to move from abstract planning to concrete execution with confidence. Designed to be audit‑ready, the framework is trusted by auditors, architects, and project managers across industries. Readers will find methodological depth combined with practical usability, making this guide a cornerstone for anyone responsible for SAP cutover success. Audience: SAP project managers, cutover managers, IT architects, consultants, and governance professionals who carry responsibility for a successful Go Live. What makes this book unique is its combination of governance, methodology, and practice in one comprehensive system. It is not just a handbook—it is a complete governance solution that equips organizations to navigate the decisive cutover phase with clarity, control, and assurance.
