Final answer:
Named Update Sets in ServiceNow allow for better tracking and management of system customizations, prevent unintended changes in production, and support clean code reviewas and audits. They must be committed after work is completed to ensure proper version control.
Step-by-step explanation:
Using Named Update Sets instead of the Default Global in ServiceNow allows for better management and version control of the customizations and configurations made within the system. Update sets are a way to group together all the changes made to the configuration records, such as new fields, form layouts, or scripts. When you use a named update set, you can easily track changes, move them between instances (from development to test and then to production), and maintain a clearer history of what changes have been made and by whom.
Moreover, by not using the Default Global update set, you avoid the risk of unintended changes being pushed to production. Each Named Update Set acts as a container for a particular project or task, ensuring that only related changes are captured. This organizational strategy will also ease the process during code reviews and audits, as it's clearer what each set of changes is attempting to accomplish.
It's important to commit update sets when the work is done so that they can be transferred properly. Uncommitted changes can lead to conflicts or loss of work. So, using Named Update Sets is a best practice in ServiceNow development for these reasons.
