Fremont, CA: Change management in information technology (IT) is a structured process for reviewing proposed IT system or service changes. This process takes place prior to implementing the requested change on an organization's network, reducing or eliminating network outages.
IT change management is required to ensure that any changes to the network do not degrade network performance. Any changes to the network should be a defined, purposeful action to remove a found vulnerability, upgrade a component on the network for improved performance, or replace a currently obsolete or faulty network component. Listed below are different types of IT change management. Let's have a look.
Standard Changes
Standard changes are routine and adhere to a pre-defined process for risk analysis and pre-approvals. These modifications are vetted processes that have been pre-approved for implementation. The following are some examples of standard changes:
• Increasing RAM or hard drive capacity
• Creating a new database instance
• Replacing a failing network device
Normal Changes
Normal changes do not follow a set procedure. Risk analysis and deployment plan must be submitted for approval before implementing these changes on the IT network. The following are some examples of normal changes:
• Changing to a new compliance management system
• Improving network performance by upgrading network devices
• Changing to a new compliance management system
Emergency Changes
An unplanned outage has occurred or is likely to occur as a result of a discovered vulnerability that poses a significant threat to the network. The following are some examples of emergency changes:
• The installation of a security patch
• The failure of a network device
• Recovering from a significant incident
