Where value can be captured
Insurance sits between policyholders seeking risk transfer, brokers or direct distribution, underwriting and claims operations, reinsurers, and capital providers. Profit depends on selection and pricing discipline as much as top-line growth.
For Willis Towers Watson, name suppliers, channels, customers and infrastructure dependencies only when a reliable source establishes the relationship. The goal is to show where the company sits, what it depends on, and where bargaining power resides.
