Allocated Baseline

AETM 003

DAU GLOSSARY DEFINITION

Documentation that designates the Configuration Items (CIs) making up a system and then allocates the system function and performance requirements across the CIs (hence the term “allocated baseline”). It includes all functional and interface characteristics that are allocated from those of a higher-level CI or from the system itself, derived requirements, interface requirements with other CIs, design restraints, and the verification required to demonstrate the achievement of specified functional and interface characteristics. The performance of each CI in the allocated baseline is described in its item performance specification.

Alternate Definition
Mainly describe by a set of item performance specifications of the higher level configuration items (CIs). Designate the configuration item performance requirements for each of the higher level configuration items. It includes function, interface, and design consideration requirements of each of the higher level configuration items.
General Information

An allocated baseline is a snap shot of the item performance specifications, internal interfaces specifications and external interface specifications.  It is the middle level of the three technical baselines. The system functions are allocated to the higher level CIs, and the functions of some of the higher level CIs are allocated to the lower level CIs.  The allocated baseline includes all functional and interface characteristics that are allocated from those of a higher-level CI or from the system itself, derived requirements, interface requirements with other CI, design restraints, and the verification required to verify the achievement of specified functional and interface characteristics.  The allocated baseline is usually established and put under configuration control at each configuration item's (hardware and software) preliminary design review (PDR), culminating in the system allocated baseline established at the system-level PDR.
