Number of relative changes amended or rejected per period and category
●

●

●
Number of relative changes that do not produce the desired business results

Change management team
You should create a change management team that includes representation from networking
operations, server operations, application support, and user groups within your organization.
The team should review all change requests and approve or deny each request based on
completeness, readiness, business impact, business need, and any other conflicts.
The team should first review each change to ensure that all associated documentation is
complete, based on the risk level. The team can then investigate the business impact issues
and business requirements. The final step is to schedule the change. Once a change has been
approved, the change management team is also responsible for communicating the change to
all affected parties. In some cases, user training might also be needed.
Note:
Note:
The change management team does not investigate technical accuracy of the
change. Technical experts who better understand the scope and the technical
details should complete this phase of the change process.
