Certified Business Analysis Professional (CBAP) — Question 458

You are creating a model that shows how data moves through a system. Each function that modifies the data in any manner is identified, decomposed to smaller levels, and the system is completely described from start to storage.
What type of a modeling technique are you using in this scenario?

Answer options

• A. Functional decomposition
• B. Data flow diagramming
• C. Work decomposition
• D. Organization modeling

Correct answer: B

Explanation

The correct answer is B, Data flow diagramming, as it specifically focuses on visualizing how data moves through the system and identifying the functions that modify it. Option A, Functional decomposition, is about breaking down functions but does not primarily address data flow. Options C and D, Work decomposition and Organization modeling, do not pertain directly to modeling data movement.
