What does a context diagram include?

• A. Systems and external entities only
• B. Boundaries and outputs only
• C. All processes and inputs
• D. All of the above

Answer: (D)

A context diagram serves as a high-level overview of a system, depicting its interactions with external entities. It typically includes systems and external entities, which represent the crucial elements that interact with the system being examined. The boundaries delineate what is included within the system versus what is external to it, while outputs indicate the information or products generated by the system that are sent out to those outside entities. Inputs, which are the information or resources received from external sources, are also typically represented. This combination of elements contributes to a comprehensive understanding of the system's functionality and its environment, making option D the most inclusive and accurate choice. Each aspect mentioned—systems, external entities, boundaries, outputs, and inputs—plays a vital role in illustrating the complete context in which the system functions. Knowing all these components allows stakeholders to grasp the system's scope and interactions effectively.
