Architecture
System
Capability
Specification
(SCS)
The structure and relationship among the components of a system. The system
architecture may also include the system’s interface with its operational
environment. A framework or structure that portrays relationships among all the
elements of missile defense systems.
The government document that translates capabilities into functional
specifications for the overall BMDS and allocates functional specifications among
the elements of the BMDS.
System Center
(SC)
A center in CMAFB responsible for the scheduling of maintenance for worldwide
sensors and supporting equipment as well as maintenance responsibility of
equipment in CMAFB.
System Concept
Paper (SCP)
OBSOLETE. For a major program, was used to summarize the results of the
concept exploration phase up to Milestone I and to describe the acquisition
strategy, including the identification of the concepts to be carried into the
demonstration and validation phase and the reasons for elimination of other
concepts. Now an Integrated Program Summary (IPS).
System
Configuration
Control Board
(SCCB)
The senior SDS configuration control board. The SCCB will manage the systemlevel
configuration of the SDS and the interfaces between elements of the SDS.
System Control Function or task of monitoring the maintenance status of assigned sensors and
computer systems.
System-Critical
Function
A function that is necessary for the successful accomplishment of the system's
mission.
System Definition
Review (SDR)
The formal review, in briefing format, for periodically deciding on updates to the
system plans for development based on estimates of the program schedules and
funding. The SDR summarizes candidate development plans and their potential
impacts on system design, cost, and schedule. The SDR provides a systemsengineering
basis for the MDA program planning activities. Following the SDR,
detailed element planning will result will result in a Configuration Control Board,
final trades, and program documentation in the PPBS.
System
Deployment
Delivery of the completed production system to the using activity.
MDA GLOSSARY, VER. 4.0 S
285
System Design (1) The process of defining the hardware and software architectures,
components, modules, interfaces, and data for a system to satisfy
specified system requirements.
(2) The result of the system design process.
System Design
Concept
An idea expressed in terms of general performance, capabilities, and
characteristics of hardware and software oriented either to operate or to be
operated as an integral whole in meeting a mission need.
System Design
Review (SDR)
Evaluates the optimization, correlation, completeness, and risks associated with
the allocated technical requirements.
System
Effectiveness
The measure of the extent to which a system may be expected to achieve a set
of specific mission requirements. It is a function of availability, dependability, and
capability.
System Evolution
Plan (SEP)
The documented plan that establishes the strategy to evolve the BMDS
capabilities over time. It reflects the BMD Acquisition Executive (AE) and Senior
Executive Council’s (SEC) development decisions; documents the current BMDS
Development Baseline; and summarizes the capability, integration and
assessment of the BMDS evolution. It identifies opportunities (items that provide
significant improvements in BMD capability), identifies challenges (impediments to
achieving opportunity), and points to promising alternatives that can overcome
those challenges.
System Families A collection or grouping of interrelated software systems in the domain that share
a set of common characteristics.
System
Generated
Electromagnetic
Pulse (SGEMP)
Transient electromagnetic radiation caused by the photoelectron emission of the
surface of an object subjected to a pulse of photon energy. Although local
fields close to the object surface may reach quite high values (kilovolts), the
primary disturbance mechanism is the flow of replacement current through the
object in order to produce charge equalization.
System
Integration Test
A live flight system-level test utilizing actual system command and control,
sensors, and weapon hardware.
System Manager A general term of reference to those organizations directed by individual
managers, exercising authority over the planning, direction, and control, of tasks
and associated functions essential for support of designated weapons or
