Example of a system context diagram. [1] A system context diagram in engineering is a diagram that defines the boundary between the system, or part of a system, and its environment, showing the entities that interact with it. [2] This diagram is a high level view of a system. It is similar to a block diagram.
The context diagram serves the purpose of "establish[ing] the information boundary between the system being implemented and the environment in which the system is to operate." [1] Further refinement of the context diagram requires analysis of the system designated by the shaded rectangle through the development of a system functional flow block ...
Example of a system context diagram. [14] Context diagrams are diagrams that represent the actors outside a system that could interact with that system. [15] This diagram is the highest level view of a system, similar to block diagram, showing a, possibly software-based, system as a whole and its inputs and outputs from/to external factors.
When problem analysis is incorporated into the software development process, the software development lifecycle starts with the problem analyst, who studies the situation and: creates a context diagram; gathers a list of requirements and adds a requirements oval to the context diagram, creating a grand "all-in-one" problem diagram.

A context model (or context modeling) defines how context data are structured and maintained (It plays a key role in supporting efficient context management). [1] It aims to produce a formal or semi-formal description of the context information that is present in a context-aware system. In other words, the context is the surrounding element for ...

N 2 chart example. [1] The N 2 chart or N 2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces.
