The document discusses various operating models for finance shared services, including captive, outsourced, hybrid, build-operate-transfer (BOT), and managed services models, each with their own merits and demerits. The captive model allows full control but has a high initial investment, while outsourcing provides short-term cost savings at the expense of control. Hybrid models combine benefits from both approaches, and the managed services model focuses on outsourcing daily operations for cost efficiency and better governance.
