Event Management contributes to service assurance by:

Event Management plays a crucial role in service assurance by gathering data for trend analysis. Through the systematic collection and monitoring of events, the process helps identify patterns, anomalies, and potential improvements in service delivery. This data allows organizations to proactively manage services by providing insights that can inform capacity planning, incident management, and service-level management. By analyzing trends, organizations can anticipate issues before they impact users and determine the effectiveness of their services, enabling better decision-making and improving overall service quality.

The other options do not contribute positively to service assurance. Ignoring performance metrics would hinder the ability to assess service health, while documenting user requests is more aligned with incident or service request management rather than event management. Finally, removing automated processes would detract from efficiency and effectiveness in monitoring events, which is contrary to the goal of maintaining smooth service operations.
