service-package

The Service Design Package (SDP) contains the core documentation of a service and is attached to its entry in the ITIL Service Portfolio.
The SDP is described in the book Service Design, one of the five books that comprises the core of ITIL.
The SDP follows the lifecycle of a service from when it is first suggested as a possibility to when it is finally retired. It is the central reference point for all documentation of a service, so it contains many links to other documents.
A description of the sort of information that should be kept in an SDP is found in Appendix A of the Service Design book.
The main categories described are:

Service lifecycle plan
Service programme
Service transition plan
Service operational acceptance plan
Overall operational strategy, objectives, policy, risk assessment and plans
Service acceptance criteria
At major stages through the life of a service, the "Service Design Package (SDP)"' will contain project plans, project progress and project outcomes, as well as the business case that justified the service or the transition of the service from one status to another.
