Service catalog items

The overall catalog is made up of a collection of discrete catalog items.

A catalog item can be a good or service. If something can reasonably be ordered by itself, it's a catalog item. If something only really makes sense as part of a greater whole, it's part of an item, rather than an item in and of itself. For example a new Dell server is a catalog item, as is a new Executive Desk.
