Certified Business Analysis Professional (CBAP) — Question 38

A software company has won a contract to implement its product for a client. As part of the implementation work, a business analyst (BA) is asked to compile information about the other client applications that will integrate with the new system and provide the information graphically. To establish the boundaries of the new system, the business leaders need to know the interfacing client applications and the type of information that will be exchanged between the existing and new systems.
Which type of diagram should the BA use?

Answer options

• A. Process
• B. Sequence
• C. Activity
• D. Context

Correct answer: D

Explanation

The correct answer is D, Context diagram, as it visually represents the system's boundaries and its interactions with external entities, making it ideal for showing interfacing applications and information exchanges. Options A, B, and C (Process, Sequence, and Activity diagrams) focus on internal processes and workflows, which do not effectively illustrate the system's boundaries or external interactions.
