Documentation & Traceability Questions
Part of the Business Analyst Roadmap
In short
'How would you structure a BRD?' and 'How do you keep requirements traceable?' are classics. Interviewers can tell quickly if you've actually written these documents or only read about them.
'Walk me through how you'd structure a BRD' or 'how do you ensure requirements traceability?' — testing genuine documentation fluency from Phase 3, not just naming document types.
Think of it like this
The dabbawala's code
Mumbai's dabbawalas move huge numbers of tiffins every day using simple marks on each box. Every tiffin is traceable from a kitchen to one desk and back. Traceability means every requirement can be followed from its source to its test, just as reliably.
Watch it happen
Answering 'how do you ensure traceability?'
1/5Start from business goals or objectives, each with an ID, like G1: cut booking time.
The big ideas
What you need to know
Know a BRD's sections
Purpose, scope, stakeholders, business requirements, assumptions, constraints, glossary, sign-off. Say them in a sensible order.
RTM, in one line
A requirements traceability matrix links each requirement to its goal, source, design or story, and tests.
Traceability enables impact analysis
Explain the 'why': when a rule changes, you can see exactly what else must change.
Use a real example
'In my canteen case study, FR-03 traced to G2 and TC-03' is far more convincing than theory.
See it in code
Walk through the code

A tiny traceability matrix. The last row shows its real value: a requirement with no test sticks out immediately.
Save yourself the pain
Common mistakes
Oops
Saying 'I just list the document types: BRD, FRD, SRS'.
Do this instead
Explain what goes in one, who reads it, and how you kept it current.
Oops
Describing traceability as just a spreadsheet you fill once.
Do this instead
Describe it as a living link you use for impact analysis and test coverage.
Your mission
Build a mini RTM
Quick check
A business rule changes mid-project. How does a traceability matrix help?
Go deeper
- 1Review Phase 3 and practice explaining the BRD/FRD structure and RTM purpose clearly.
- 2Prepare to discuss your Phase 3 practice BRD project if you built one.
- 3Practice explaining why traceability matters concretely, with a specific example.
