Cross-Cutting Systems Engineering Methods Flashcards
What are the purposes that models can serve throughout the system life cycle?
Characterizing an existing system; mission and system concept formulation and evaluation; system architecture design and requirements flowdown; support for systems integration and verification; support for training; knowledge capture and system design evolution.
Page 588-590
In which system life cycle processes can we use models and simulations?
Business or mission analysis, requirements definition, architecture definition, design definition, verification and validation, operations.
Page 592
What should be determined to address the model’s intended purpose for each type of model?
The appropriate breadth, depth and fidelity.
Page 592
What does the model’s fidelity indicate?
It indicates the level of detail the model must represent for any given part of the model.
Page 594
What model classes are listed in the taxonomy shown in the SE Handbook?
Physical mock-ups, abstract models, informal models, formal models.
Page 596
Give some examples of system models.
Functional model, behavioral model, temporal model, structural model, mass model, layout model, network model.
Page 598
Give some examples of simulations types.
Physical simulations, computer-based simulations, hardware and/or human-in-the-loop simulations.

Give an example of one approach to semantic interoperability.
To use model transformations between different models.

What are the SysML diagram types?
Package diagram, requirements diagram, system structure (block definition diagram, internal block diagram), behavior (use case diagram, activity diagram, sequence diagram, state machine diagram), parametric diagram.

What is MBSE defined in INCOSE Systems Engineering Vision 2020?
It is the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases.

What are benefits of MBSE?
Improved communications, increased ability to manage system complexity, improved product quality, enhanced knowledge capture and reuse of the information, improved ability to teach and learn SE fundamentals.
Page 614-616
Give examples of candidate MBSE methodologies.
INCOSE Object-Oriented Systems Engineering Method (OOSEM), IBM Rational Telelogic Harmony-SE, IBM Rational Unified Process for Systems Engineering (RUP-SE), Vitech MBSE Methodology, JPL State Analysis (SA), and Dori Object-Process Methodology (OPM).

What is FBSE?
It is an approach to SE that focuses on the functional architecture of the system.
Page 618
What is the objective of FBSE?
To create a functional architecture for which system products and processes can be designed and to provide the foundation for defining the system architecture through the allocation of functions and subfunctions to hardware/software, databases, facilities, and operations.
Page 618
What are the key outputs generated from FBSE?
IPO diagrams, behavior diagrams, control flow diagrams, data flow diagrams, entity relationship diagrams, functional flow block diagrams, integrated definition for functional modeling diagrams, data dictionaries, models, simulation results.
