Systems Engineering Process Flashcards
It is a comprehensive, iterative, and recursive
problem-solving process, applied sequentially top-down by
integrated teams.
Systems Engineering Process
It transforms needs and requirements into a set of system product and
process descriptions, generates information for decision-makers, and provides
input for the next level of development.
Systems Engineering Process
The process is applied sequentially, one level at a time, adding
additional detail and definition with each level of development.
Systems Engineering Process
is one of the first activities of the System Engineering
Process and functions somewhat as an interface between the
internal activities and the external sources providing inputs to
the process.
Requirements Analysis
It examines, evaluates, and translates the external inputs into a set of functional
and performance requirements that are the basis for the Functional Analysis and
Allocation.
Requirements Analysis
It links with the Functional Analysis and Allocation to form the requirements loop
of the System Engineering Process.
Requirements Analysis
Its goal is to determine the needs
that make up a system to satisfy an overall need.
Requirements Analysis
manages and controls the
overall Systems Engineering Process.
System Analysis and Control
This activity identifies the work to be performed and develops the schedules and
costs estimates for the effort.
System Analysis and Control
It coordinates all activities and assures that all are operating from the same
set of requirements, agreements, and design iteration.
System Analysis and Control
It’s the center for
configuration management throughout the systems engineering process.
System Analysis and Control
is a top-down process of translating system-level requirements
into detailed functional and performance design criteria.
Functional Analysis and Allocation
The result of the process is a defined Functional Architecture with allocated system requirements that are traceable to each system function.
Functional Analysis and Allocation
to lower-level functions is the incoming
interface for the Requirements Loop.
Decomposition
The functions identified in the Requirements Analysis are analyzed to define successively lower-levels of functions that accomplish the higher-level functional requirements
Decomposition
All requirements of the top-level functions must be allocated for all lower-level functions.
Allocation
It is an on-going record of the pedigree of requirements imposed on system and subsystem elements. Because requirements are derived or apportioned among several functions, they must be traceable across functional boundaries to parent and child requirements
Traceability
is the process of taking the functional
architecture developed in the Functional Analysis and Allocation step and decomposing those functions into
a Physical Architecture (a set of product, system, and/or software elements) that satisfy system required functions.
Design Synthesis
It is the process whereby the Functional Architectures and
their associated requirements are translated into physical
architectures and one or more physical sets of hardware, software,
and personnel solutions.
Synthesis
It is the output end of the Design Loop.
Synthesis
It is a traditional term. Despite the name, it includes software elements as well as hardware elements.
Physical Architecture
the primary output of Design Synthesis
Physical Architecture
It is developed from the physical architecture.
