BA Role Tools and Technologies 3 — Questions and Answers
Question 1: A BA wants to document the boundary between a new inventory system and external systems it interacts with. Which diagram is best suited for this?
- Swimlane diagram
- Context diagram (Correct answer)
- Data flow diagram Level 1
- Gantt chart
Correct answer: Context diagram
A context diagram shows the system as a single process surrounded by external entities and the data flows between them, clearly defining the system boundary.
Question 2: In Microsoft Azure DevOps, which work item type is used to track a customer-facing feature deliverable that spans multiple sprints?
- Task
- Bug
- Feature (Correct answer)
- Test case
Correct answer: Feature
In Azure DevOps, a Feature groups related User Stories under a deliverable outcome, sitting above stories and below Epics in the hierarchy.
Question 3: A BA exports stakeholder survey results into Excel and needs to identify which issues appear most frequently. Which built-in Excel feature is most efficient?
- Conditional formatting gradient scale
- COUNTIF function with a summary table (Correct answer)
- Goal Seek
- VLOOKUP to a static list
Correct answer: COUNTIF function with a summary table
COUNTIF tallies how many times each issue appears in a column, making frequency analysis fast and accurate.
Question 4: Which prototyping approach shows only navigation flows and element placement without colors or final content, used to validate structure early?
- High-fidelity prototype
- Wireframe (low-fidelity) (Correct answer)
- Functional prototype
- Clickable mockup
Correct answer: Wireframe (low-fidelity)
Wireframes represent layout and navigation with minimal visual detail, allowing rapid feedback on structure before investing in design.
Question 5: When a BA uses Balsamiq to create mockups, what characteristic best describes its output?
- Pixel-perfect UI ready for developer handoff
- Deliberately rough sketchy visuals that discourage premature design discussions (Correct answer)
- Fully interactive coded prototypes
- Automated user acceptance test scripts
Correct answer: Deliberately rough sketchy visuals that discourage premature design discussions
Balsamiq's intentionally hand-drawn look signals that the design is not final, keeping stakeholder feedback focused on functionality rather than aesthetics.
Question 6: A BA needs to model how data transforms as it moves through processes in a system. Which artifact is most appropriate?
- Use case diagram
- Data flow diagram (DFD) (Correct answer)
- Class diagram
- Gantt chart
Correct answer: Data flow diagram (DFD)
DFDs show how data enters, moves through, gets transformed by, and exits processes and data stores in a system.
Question 7: In Salesforce CRM, a BA wants to understand which fields are populated versus empty across 10,000 accounts. Which built-in feature helps most?
- Workflow rules
- Reports with field-level summary and null filters (Correct answer)
- Approval processes
- Permission sets
Correct answer: Reports with field-level summary and null filters
Salesforce Reports can filter on blank/non-blank field values and show record counts, enabling a BA to audit data completeness across the org.
