Question:

Q7.2. When reviewing the level 2 data flow diagrams (DFDs) that were created by the business analyst, the customer noticed that there was data coming in from the federal government, which had not been previously specified.

How would you respond to that if you were the business analyst?

(a) Good catch. We’ll submit it as a change control to the level 0 and level 1 DFD and evaluate the impact.

(b) Good catch. We’ll update the level 0 and level 1 DFD.

(c) It is normal that you discover more data flows as you decompose a DFD. It’s just part of the process.

(d) As long as a data flow from an external entity, over which you have no control, shows up in at least one level of the DFD, you are OK.
