This document summarizes Carnival Corporation's growth from a single ship company in 1972 to the largest cruise company in the world today operating over 100 ships across multiple brands. It discusses Carnival's portfolio of cruise brands, its market share compared to other regions, and opportunities for continued growth in the Australian market. The document also presents two case studies, one on a past customer service restructure and another on a planned operating model realignment, to examine lessons learned from previous change management efforts and how those lessons are being applied to future planning.
