This document discusses how to build a business case for data center transformation (DCT) to gain support from the C-suite. It recommends defining the current state of high costs and complexity, the future state of reduced costs and improved services through consolidation and standardization. The business case should show how DCT will reduce overall IT costs, shift spending to business priorities, and improve business continuity. Workshops are suggested to determine benefits, critical success factors, and clarify business and IT priorities to get projects started and gain stakeholder buy-in.
