Preparing documentation is one of the most important responsibilities of a Business Analyst. This blog covers essential interview questions related to BRDs, FRDs, and Use Cases in a simple, easy-to-understand question–answer format. These questions help you revise quickly and prepare confidently for Business Analyst interviews.
BRD Interview Questions
Question 1. What is a Business Requirements Document (BRD)?
Answer: A BRD is a high-level document that describes the business needs, objectives, current challenges, and expected outcomes of a project. It outlines what needs to be built from a business perspective without technical details.
Question 2. What are the key components of a BRD?
Answer: Components include project overview, business goals, scope, out-of-scope items, assumptions, constraints, stakeholders, high-level requirements, workflows, and acceptance criteria.
Question 3. How do you gather requirements for a BRD?
Answer: Requirements are gathered using interviews, workshops, surveys, observations, document analysis, stakeholder meetings, and brainstorming sessions.
Question 4. How do you ensure a BRD aligns with business objectives?
Answer: By validating requirements with stakeholders, connecting each requirement to business goals, prioritizing based on value, and eliminating non-essential features.
Question 5. What are common mistakes in writing a BRD?
Answer: Adding technical details, unclear requirement statements, missing scope definition, lack of stakeholder sign-off, and not updating the BRD when requirements change.
FRD Interview Questions
Question 6. What is a Functional Requirements Document (FRD)?
Answer: An FRD details how the system should work. It includes system behaviors, data flow, business rules, input and output formats, and integration logic.
Question 7. How is an FRD different from a BRD?
Answer: A BRD explains what the business needs, while an FRD explains how the system will fulfill those needs. BRD is business-focused; FRD is solution-focused.
Question 8. What elements are typically included in an FRD?
Answer: Functional requirements, non-functional requirements, workflows, UI mockups, data models, validation rules, error-handling rules, and integration points.
Question 9. How do you validate an FRD?
Answer: By reviewing it with technical teams, QA testers, and business stakeholders. Using a Requirements Traceability Matrix ensures full coverage.
Question 10. What challenges occur when writing FRDs?
Answer: Unclear business requirements, scope changes, communication gaps, technical limitations, and missing details that cause misunderstandings during development.
Use Case Interview Questions
Question 11. What is a Use Case?
Answer: A Use Case describes the interaction between a user and a system to achieve a specific goal. It details user actions, system responses, and event flows.
Question 12. What are the main components of a Use Case?
Answer: Use case name, description, actors, triggers, preconditions, basic flow, alternate flows, exception flows, and postconditions.
Question 13. How do you identify actors in a Use Case?
Answer: Actors are identified by determining who interacts with the system—users, external systems, or internal services that initiate or receive actions.
Question 14. How do Use Cases support requirement documentation?
Answer: They clarify system behavior, assist developers in understanding workflows, help QA teams create test scenarios, and reduce miscommunication.
Question 15. What is the difference between Use Cases and User Stories?
Answer: User stories are short and value-focused, while Use Cases are detailed and cover multiple flows, including exceptions.
General Questions on Documentation and Requirements
Question 16. How do you keep documentation updated throughout the project?
Answer: By maintaining version control, conducting review meetings, collaborating with teams, and updating documentation whenever changes are officially approved.
Question 17. What tools are commonly used for BRDs, FRDs, and Use Cases?
Answer: Confluence, JIRA, MS Word, MS Visio, Lucidchart, Draw.io, Figma, and requirement management systems like Jama and Azure DevOps.
Question 18. What is a Requirements Traceability Matrix (RTM)?
Answer: An RTM maps business requirements to functional requirements, design elements, and test cases, ensuring all requirements are implemented and validated.
Question 19. How do you manage conflicting requirements?
Answer: By facilitating stakeholder discussions, analyzing business impact, prioritizing based on value, and escalating to decision-makers when needed.
Question 20. What qualities make a strong Business Analyst?
Answer: Strong communication, analytical thinking, documentation skills, problem-solving ability, attention to detail, and the ability to translate business needs into clear requirements.
Conclusion
Clear documentation is the foundation of successful projects. Understanding BRDs, FRDs, and Use Cases helps Business Analysts guide teams effectively and avoid miscommunication. Practicing these interview questions prepares you to confidently explain documentation processes during interviews.
