Systems Engineering Process Flashcards
?
– is a comprehensive, iterative, and recursive problem-solving process, applied sequentially top-down by integrated teams.

Systems Engineering Process
– is a comprehensive, iterative, and recursive problem-solving process, applied__ by __.
- sequentially top-down
- integrated teams
?
– It transforms needs and requirements into a set of system product and process descriptions
– generates information for decision-makers
– provides input for the next level of development
Systems Engineering Process
Systems Engineering Process
– It transforms __ into a set of __ and __
– generates__ for __
– provides__ for the __
-needs and requirements
-system product and process descriptions
- information
-decision-makers
- input
-next level of development
?
The process is applied __, one level at a time, adding __ and __ with __.
Systems Engineering Process
-sequentially
-additional detail and definition
-each level of development
Four Steps that Comprise the SE Process:
Requirements Analysis
System Analysis Control
Functional Analysis/Allocation
Design Synthesis
?
– is one of the first activities of the System Engineering Process and functions somewhat as an__between the__ and the __providing __ to the process.
Requirements Analysis
- interface
- internal activities
- external sources
- inputs
?
– It __,__, and__ the __into a set of __ and __ that are the basis for the __.
Requirements Analysis
-examines, evaluates, and translates
-external inputs
-functional and performance requirements
-Functional Analysis and Allocation
?
– It links with the __ to form the __ of the System Engineering Process.
Requirements Analysis
-Functional Analysis and Allocation
-requirements loop
?
– The goal of __ is to determine the __that make up a system to satisfy an __
Requirements Analysis
-requirements analysis
-needs
-overall need.
– __manages and controls the overall Systems Engineering Process.
System Analysis & Control
?
– This activity identifies the __ and develops the __ and __ for the effort.
System Analysis & Control
-work to be performed
-schedules and costs estimates
?
– It__ all activities and assures that all are operating from the same set of __,__,and__.
- coordinates
-requirements, agreements, and design iteration
?
– It’s the __ throughout the systems engineering process.
System Analysis & Control
-center for configuration management
?
– is a __of translating __ into detailed __ and __ criteria.
Functional Analysis and Allocation
-top-down process
-system-level requirements
-functional and performance design
?
– The result of the process is a defined __ with __ that are __to each system function.
Functional Analysis and Allocation
-Functional Architecture
-allocated system requirements
-traceable
-system function
Decomposition
– to __ is the __ for the __.
-lower-level functions
-incoming interface
-Requirements Loop
?
– The __ identified in the __are analyzed to define successively __ that accomplish the__
Decomposition
-functions
-Requirements Analysis
- lower-levels of functions
-higher-level functional requirements
?
– All requirements of the __must be allocated for all lower-level functions.
Allocation
-top-level functions
-lower-level functions
__is an on-going record of the __ imposed on __ and __..
Traceability
-pedigree of requirements
-system and subsystem elements
Because requirements are __ or __among several functions, they must be __ across __ to __.
-derived or apportioned
-traceable
-functional boundaries
-parent and child requirements
?
– the process of taking the __ developed in the __ and __ into a __ (a set of __,__, and/or __) that satisfy __.
Design Synthesis
-functional architecture
-Functional Analysis and Allocation step
-decomposing those functions
-Physical Architecture
- product, system, and/or software elements
- system required functions
– It is the output end of the Design Loop.
Synthesis
?
– is the process whereby the __ and their __are translated into __ and one or more __,__, and __.
Synthesis
-Functional Architectures
-associated requirements
-physical architectures
-physical sets of hardware, software, and personnel solutions
?
– is a traditional term. Despite the name, it includes __as well as __.
Physical Architecture
-software elements
-hardware elements
the primary output of Design Synthesis
Physical Architecture
characteristics of the physical architecture
-The correlation with functional analysis requires that each physical or software component meets at least one (or part of one) functional requirement, though any component can meet more than one requirement
-The architecture is justified by trade studies and effectiveness analyses
-A product Work Breakdown Structure (WBS) is developed from the physical architecture
-Metrics are developed to track progress among Key Performance Parameters (KPP)
-All supporting information is documented in a database.
