(SE Handbook Ch.1-4) 100% Correct
Answers | Verified | Latest 2024 Version
System Concept - ✔✔A shared mental representation of the actual system
System elements have processes that have the binary value of ______ or _____ - ✔✔idle, execute
System elements cannot be systems on their own merit. (True/False) - ✔✔False
What are two things that integration must establish? - ✔✔1. relationships between the effects that
organizing the elements has on their own interaction.
2. How these effects enable the system to achieve its purpose
In defining a hierarchy, a SE must strike a balance between: - ✔✔1. Defining span of control clearly and
simply
2. Resolving the structure of the SOI into a complete set of system elements that can be implemented
with confidence
Characteristics that can be used to decide if SOI is better understood as a SoS - ✔✔o Operational
independence of constituent system
o Managerial independence of constituent system
o Geographical distribution
o Emergent behavior
o Evolutionary development process
In complicated systems, the interactions between many parts are governed by______. - ✔✔fixed
relationships
,Difference between complex and complicated systems - ✔✔o In complicated systems, the interactions
between many parts are governed by fixed relationships.
o In complex systems, interactions between the parts exhibit self-organization where local interactions
give rise to novel. Nonlocal, emergent patterns.
o Complicated systems can often become complex when behavior patterns change.
Challenges that influence the engineering of an SoS - ✔✔o SoS Authorities (each constituent system has
its own local owner)
o Leadership
o Constituent systems' perspectives
o Capabilities and requirements (most SoS are made up of multiple independent systems with their own
requirements),
o Autonomy, interdependencies, and emergence
o Testing, validation, and learning
o SoS principles (new field, major learning curve for traditional SEs)
o Security challenges
What should be considered during life cycle stages of the SOI? - ✔✔Relevant enabling systems
One system variable can be the cause and effect of another system due to - ✔✔circular causation
What are the three classes of SE competencies? - ✔✔Systems thinking
Holistic life cycle view
SE management
Operating environment/ Operating Context - ✔✔collection of elements that interact with the system
Attribute - ✔✔observable characteristic/property of a system
System Boundary - ✔✔what belongs/does not belong to the system
, Functionality - ✔✔interactions of the system with its operating environment
System Architecture - ✔✔per IEEE 42010 (2011): "the fundamental concept or properties of a system in
its environment embodied in its elements, relationships, and in the principles of its design and
evolution."
Variable - ✔✔symbol/name that identifies an attribute
Measurement - ✔✔outcome of a process in which the SOI interacts with an observation system under
specified conditions.
Dynamic behavior - ✔✔time evolution of the system state
Emergent behavior - ✔✔behavior of the system that cannot be understood exclusively in terms of the
behavior of individual system elements.
· Black Box/ White Box - ✔✔- Black box: external view of the system (attributes)
- White box: internal view of the system (attributes and element structure)
Partitioning of the system - ✔✔identify a complete set of distinct system elements with regard to only
the whole by suppressing details of their interactions and interrelations
System Hierarchy Concept - ✔✔per IEEE 15288: "[5.2.2] The system life cycle processes...are described in
relation to a system that is composed of a set of interacting system elements, each of which can be
implemented to fulfill its respective specified requirement."
SoS - ✔✔an SOI whose elements are managerially and/or operationally independent systems
Enabling systems - ✔✔systems that facilitate the LC activities of the SOI
