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