The Service Portfolio is described in the ITIL books Service Strategy and Service Design. The Service Portfolio is the core repository for all information for all services in an organization. Each service is listed along with its current status and history. The main descriptor in the Service Portfolio is the Service Design Package (SDP).
The Service Portfolio consists of three parts:
This contains references to services that are not yet live. They may be proposed, or under development
This contains links to active services through their Service Design Package
Services in the process of being discontinued, before they are finally decommissioned
Of these three, only the Service Catalogue is visible to the customers and support team. Customers are excluded from the pipeline provisioning process for services under development.
