Whether you are a business analyst, business architect, project manager, or project sponsor, context model is an easy and efficient tool. Use it to direct the discussion, avoid confusion, identify missed stakeholders, clear up misunderstandings before they derail the project.
You have understood the context model in software engineering. The context model is an external perspective model that shows the interaction between the main system and other systems with the help of graphical notation.
The context model takes into account the relationships between words and their surrounding text, helping the language model understand the meaning of a word in a specific context, handle ambiguities, and generate more accurate and coherent responses.
Context diagrams serve as a foundational tool, helping designers and stakeholders grasp the scope and boundaries of a system under consideration. These diagrams provide a high-level view, illustrating how the system interacts with external entities and the environment.
Definition by Gasparic et al. [63]: “A context model is a set of contextual factors that characterize a situation”. Preeja Pradeep, Shivsubramani Krishnamoorthy, in Computer Communications, 2019. An ideal context model should incorporate the best features and characteristics of existent context models.
Context models are used to illustrate the operational context of a system - they show what lies outside the system boundaries. Social and organizational concerns may affect the decision on where to position system boundaries.
Use case diagrams: interactions between a system and its environment. Sequence diagrams: interactions between actors and the system and components. Class diagrams: classes in the system and the associations between these classes. State diagrams: how the system reacts to events.

System Context Diagrams play a vital role in software development by providing a high-level visual representation of a system’s context. They help in effective communication, scope definition, requirements analysis, and design, serving as a foundational tool that guides the development process.
The purpose of the context model is to understand the environment in which the system will work, along with the support of the surrounding systems. Software developers develop various architectural models illustrating the system and its association with other systems.
