User annotation should ideally be used to explain why you designed your workspace in a particular way.

• A. Not applicable
• B. Sometimes
• C. False
• D. True

Answer: (D)

Clear workspace documentation through user annotations helps others understand why you arranged the design the way you did. Annotations capture the rationale behind decisions—why a transformer is placed here, why a filter criteria was chosen, or why data is joined in a particular sequence—so the intent isn’t lost as you or someone else revisits the project. This context speeds maintenance, debugging, and collaboration, since future readers can follow the reasoning without guessing. Annotations also aid onboarding and knowledge transfer, making it easier to modify the workspace while preserving the original intent. They don’t affect data flow or performance; they are purely there to communicate intent. For that reason, using user annotation to explain design choices is best practice.
