INCOSE CH 9 Exam Questions And
Answers |Latest 2025 | Guaranteed Pass
Why do stakeholders of the SE life cycle use models and simulations? - Answer✔1) Check their
own thinking 2) communicate their concepts to others
What are the benefits of models and simulations? - Answer✔1) Confirm the need for the
systems and the anticipated system behaviors before proceeding with development of the
actual system 2) present a clear, coherent design to those who will develop, test, deploy and
evolve the system.
What is the objective of models and simulations early in the SE life cycle? - Answer✔obtain
information about the system before significant resources are committed to its design,
development, construction, verification or operation
What is a model? - Answer✔1) abstraction or representation of a system, entity, phenomenon
or process of interest 2) a representation of some entity in the physical world 3) represents a
system and its environment is of particular importance
What is a simulation? - Answer✔1) implementation of a model or models in a specific
environment that allows the model's execution or use over time 2) a means of analyzing
complex dynamic behavior of systems, software, hardware, people and physical phenomena
What is the purpose of modeling? - Answer✔a) characterizing an existing system b) mission and
system concept formulation and evaluation c) system architecture design and requirements

flow down d) support for systems integration and verification e) support for training f)
knowledge capture and system design evolution
What are the types of models? - Answer✔physical mock-ups (actual system), abstract models,
informal models and formal models (geometric, quantitate, logical)
What is a system model used for? - Answer✔to represent a system and its environment
What are some examples of system models? - Answer✔functional models (functions and
functional interfaces), behavioral models, temporal models (timing-related aspects), structural
models (system elements and their physical interfaces), mass models, layout models (absolute
and relational spatial placements) and network models (flow of resources)
What are the types of simulations? - Answer✔physical, computer-based, and hardware and/or
human-in-the-loop
What is a live simulation? - Answer✔live operators operating real systems
What is a virtual simulation? - Answer✔live operators operating simulated systems
What is a constructive simulation? - Answer✔simulated operators operating with simulated
systems
What process certifies that a model or simulation is acceptable for use? - Answer✔verification,
validation and accreditation (VV&A)
What ensures that a construct in one model has the same meaning as a corresponding
construct in another models? - Answer✔semantic interoperability
