Final answer:
Update Sets in ServiceNow are used to manage changes in an instance's configuration. Previewing an Update Set before committing is crucial to identify conflicts and ensure smooth implementation. This process is significant in maintaining the integrity and functionality of the system.
Step-by-step explanation:
The term Update Sets is typically associated with the cloud computing platform ServiceNow. Update Sets are a mechanism for grouping and managing changes made to an instance's configuration and customization. The process involves capturing customized components such as new applications, modules, fields, or workflow edits into an Update Set, which can be moved from one instance to another, for example, from a development instance to a production instance.
Before an Update Set is committed to the target instance, it is crucial to preview it. Previewing an Update Set allows administrators to identify and address any conflicts or issues that may arise when transferring the set. This step is necessary to ensure a smooth implementation of new features or configurations without disrupting the existing system operation.
