However this standard should not be treated as comprehensive, there are obvious omissions. Some are recently emerging sectors, some are implied and some are just not listed. The primary ones are Real-time Application Relationship Discovery which supports Configuration Management, Security Information and Event Management functions (known as SIEM), Workload Scheduling, Business Impact functions (also known as Business Systems Management) and Capacity Management. Performance Management functions can also be split into end-to-end performance measuring and infrastructure component measuring functions.
