Impact simulation of changes to configuration items

This use case describes how to simulate the impact of changes to configuration items (CIs) on other CIs in the IT environment of an organization so that well-informed decisions can be taken to address issues related to changes.

Impact simulation scenario

Scenario

Calbro Services needs to identify the impact of restarting a server when addressing an incident. They want their incident manager to run a simulation that shows the impact of restarting the server on other configuration items (CIs) so that they can work on an appropriate solution.

Harry, an incident manager at Calbro Services has been assigned to an incident for an accounting program that is not working. He identifies that the issue is being caused by a faulty database, and determines that he must update the database and restart the server to bring the program back online.

Before Harry restarts the server, he runs a simulation in CMDB Impact Simulator to determine the impact of restarting the server on other CIs. For example, there might be other software on the server unrelated to the issue he is trying to fix.

The results of the simulation show that restarting the server will also impact human resources software using a different, and currently functional, database on the same computer. With this knowledge, the Harry presents the issue and solution to the Emergency Change Advisory Board at Calbro Services.

CMDB Impact Simulator

Incident manager

Find the CIs whose impact you want to simulate, run the simulation and view the results.

Create a report of the impact simulation results.


Impact simulation results

Impact simulation helps predict potential disruptions to services and help provide preventive actions to various problems that arise in businesses when certain CIs are either unavailable or in some state of impairment. 

Impact simulation benefits

Assessing the impact of changes to CIs to various other CIs and services provides the information required to address various changes in the IT environment helps maintain vital business services.
