cathi walker

I've led SAP S/4HANA, cloud, and enterprise modernization programs for Southern California Edison, The Walt Disney Company, Accenture, Dominion Energy, and Capgemini. My work spans business cases, technology due diligence, architecture, delivery planning, go-live, stabilization, and executive advisory.

At Southern California Edison, I led cutover governance and go-live execution for a $1.5B SAP S/4HANA finance and customer platform transformation. At Disney, I provided architecture and transformation leadership for a ~$250M global SAP finance modernization, shaping roadmaps across SAP S/4HANA Finance, Datasphere, SAP Analytics Cloud, AI-enabled planning, and Clean Core governance.

I've directed portfolios exceeding $2B in aggregate value, reduced total cost of ownership by 25% through rationalization and operating-model redesign, and translate architecture, risk, and investment decisions for CFOs, CIOs, and boards. I also bring current AI transformation development focused on readiness, use-case prioritization, governance, implementation, adoption, and value realization.
