When necessary changes to the base product can be made without having these changes affect any versions. When a product version is created its content are separate from the main base product. This allows the course developer to continue to work and update the base content as desire without affecting the live version assigned to the leaners.
It is possible to make changes directly in the versioned content, depending on the nature of the change. For example if one typographical error needed to be corrected the change might be made directly in the version (as well as in the base) to avoid having to do a full refresh of all of the content.
If changes from the base product are necessary to be updated to the live version, the course developer may decide to refresh the version.
