Final answer:
A Service Catalog is a comprehensive document listing all IT services and software with their respective support contacts within an organization, serving as a key component in IT Service Management.
Step-by-step explanation:
A Service Catalog is a document (preferably online) that lists every service and software package supported within an organization, plus the names of first- and second-level support contacts for those services or software packages. This catalog serves as a central source of information on the IT services delivered to the business by the IT service provider. It helps in aligning IT resources with the needs of the business, and ensures that the services provided are easily accessible to those who need them.
The Service Catalog typically includes details such as service descriptions, pricing, service-level agreements (SLAs), and information about ordering and requesting services. It is a key component of IT Service Management (ITSM) and serves as a bridge between the IT organization and its customers.
