1.3 Systems Concepts Flashcards
What is the collection of elements within an external view of a system?
The collection of elements is called system environment or context and can include the users (or operators) of the system. It is not limited to the operating environment but also includes external systems that interface with or support the system at any time of the life cycle.
What do the internal and external views of a system give rise to?
The system boundary. It is a line of demarcation between the system under consideration, called the systems of interest (SoI) and its greater context.
How is the functionality of a system typically expressed ?
It is expressed in terms of the interactions of the system with its operating environment, especially the users. When a system is considered an integrated
What does the concept of system architecture, which ISO/IEC/IEEE 42020 (2019) define system architecture as?
Fundamental concepts or properties of an entity in its environment and governing principles for the realization and evolution of this entity and its related life cycle processes.
Section 1.3.1 System Boundary and the System of Interest (SoI)
In general, what can engineering be regarded as?
The practice of creating and sustaining systems, services, devices, machines, structures, processes, and products to improve the quality of life—getting things done effectively and efficiently.
Section 1.3.1 System Boundary and the System of Interest (SoI)
What term is used to describe an observable characteristics or property of the system?
An attribute.
What term is used to describe a symbol or name that identifies an attribute?
A variable.
What is the term for the outcome of a process in which the SoI interacts with an observed system under specified conditions?
A measurement.
What is term is used when the values assigned to its attributes remain constant or steady for a long period of time?
A state.
Section 1.3.1 System Boundary and the System of Interest (SoI).
What is emergent behavior?
It is the behavior of the system that cannot be understood exclusively in terms of the behavior of individual system elements.
Section 1.3.1 System Boundary and the System of Interest (SoI)
What is the term for the phenomenon that whole entities exhibit properties which are meaningful only when attributes to the whole, not its elements?
Emergence.
Section 1.3.2 - Emergence.
What are interoperating systems?
Interfacing systems that interface with the SoI in its operating environment to perform a common function that supports the SoI’s primary purpose.
Section 1.3.3 - Interfacing Systems, Interoperating Systems, and Enabling Systems.
What are external systems?
Systems beyond (or outside) the boundary of the SoI.
