An event manager, solely responsible for all logistics for 30 events in three weeks, made a major booking error. This demonstrates that assigning high-volume, complex projects to a single person without support turns them into a single point of failure, making critical mistakes almost unavoidable.

To mitigate client concentration risk, the quantity of relationships you maintain within a single customer account must be directly proportional to the revenue it generates. Relying on one or two contacts is a critical failure point, especially during leadership changes, transforming generic advice into a specific, quantifiable strategy for account security.
