A service catalog, is an organized and curated collection of any and all business and information technology related services that can be performed by, for, or within 3DN.
Rationale: Service catalogs act as knowledge management tools for the employees and consultants of an enterprise, allowing them to route their requests for and about services and service-related topics to the subject matter experts who own, are accountable for, and operate them. Each service within such service catalogs is usually very repeatable and has controlled inputs, processes, and outputs.
Service catalogs also allow leadership and management, for example the Chief Operations Officer (COO), to compartmentalize the enterprise into highly structured and more efficient operational units, hence the descriptive phrase: "a service-oriented enterprise."
