When should a review of service maps be particularly crucial?

A review of service maps is particularly crucial after significant infrastructure changes because these changes can impact the way services are delivered and how components interact with each other. Infrastructure modifications, such as adding new servers, removing outdated hardware, or changing network configurations, can alter the dependencies and relationships among various services.

Updating the service maps in response to these changes ensures that the organization maintains an accurate representation of its service architecture, which is essential for effective incident management, problem resolution, and planning for future capacity. If service maps are not revised following these significant changes, it could lead to misunderstandings of how services are interconnected, resulting in potential downtime, inefficient troubleshooting, and misaligned resources. Therefore, conducting a review after major infrastructure changes is crucial for sustaining operational continuity and service reliability.
