Cornelius Greyling
Cornelius Greyling is the author of Designed to Drift: Why SAP Transformations Fail Quietly. He presented the broader Program Drift framework at the 18th UT Dallas Project Management Symposium, is scheduled to present the topic to the UT System PMO Community of Practice in August 2026, and his related paper is scheduled for publication in the August 2026 edition of the PM World Journal.
He has led and supported complex S/4HANA, SAP Banking, data transformation, and multi-workstream ERP programs, including engagements involving international teams, demanding integration environments, and high-pressure delivery constraints. His work focuses on the point where formal governance remains visible, yet real control quietly weakens through misalignment, delayed decisions, and execution moving on assumptions.
Designed to Drift reflects that practitioner perspective: a delivery-grounded view of how major transformations lose control quietly, and what leaders can do to detect it sooner.
His current work extends the Program Drift argument into Program Integrity: a practical discipline for protecting coherence when large transformation programs are under delivery pressure.
Hands-on, executive-facing, delivery-grounded.
Cornelius works at the intersection of architecture discipline, transformation governance, program leadership, and delivery reality. He is especially interested in the point where visible governance continues, yet real control quietly weakens because decision flow slows, closure degrades, and execution moves on assumption instead of shared reality.
Designed to Drift reflects that practitioner perspective, together with his ongoing work around DriftBearing and DriftShield.
