Service Catalog for end users Service Catalog enables you to view and order items from departments within your organization. These catalog items can include goods, services, and information. Anything that can be ordered individually can be ordered as a catalog item. Anything that only exists as a part of a larger whole cannot be a catalog item. For example, a laptop can be a catalog item, but a high-resolution display for a laptop cannot. After placing an order, the customer can track its progress. Predefined groups follow a series of tasks to deliver the item, based on a fulfillment process, including any approvals required.
