According to ServiceNow Service Catalog best practices, migrating " as-is " from a legacy system often carries over inefficient processes and " catalog sprawl. " The recommended approach is to Review existing items to identify commonalities. By doing so, administrators can use Variables and Variable Sets to create dynamic, flexible items that serve multiple purposes. This reduces the total number of items to maintain, simplifies the user experience, and ensures that the catalog remains scalable. Combining items based on shared workflows or data requirements is more efficient than simply grouping them into Order Guides or maintaining redundant, individual items.
