Costa Crociere S.p.A. is a subsidiary of Carnival Corporation & plc, the biggest provider of Cruises worldwide. At two European locations Costa offers complex services to support ensure the operation of Costa Cruise ships. In our mission we had to plan the merge of these two functions in a new public listed company at a new location. After a in depth analysis of the existing processes a new optimised organisational structure has been defined. In parallel we developed a transition plan which included a risk mitigation strategy to ensure continuous operation of the running business.
