It helps stakeholders understand the proposed solution.
Q187. What is a Wireframe?
A Wireframe is a simple screen layout showing where major elements will appear.
Q188. Wireframe vs Prototype?
Wireframe: Basic structure.
Prototype: More realistic interaction or flow.
Q189. Why should a BA know prototyping?
A visual screen can make requirements easier to understand than long text.
Q190. What tools can be used for wireframes?
Common tools include:
Figma
Balsamiq
Draw.io
The BA only needs enough knowledge to explain the requirement clearly.
API Basics
Q191. What is an API?
API stands for Application Programming Interface.
It allows two applications to exchange information.
Q192. Give a simple API example.
An e-commerce app may call a payment service API to process a payment.
Q193. What is a REST API?
A REST API is a common way for applications to communicate over HTTP.
Q194. What is an API request?
An API request is information sent from one system to another asking for data or an action.
Q195. What is an API response?
An API response is the result returned after the request is processed.
Q196. What is an endpoint?
An endpoint is the address used to access a specific API function or resource.
Q197. What is GET?
GET is generally used to retrieve data.
Q198. What is POST?
POST is generally used to create or submit new data.
Q199. What is PUT?
PUT is commonly used to replace or update a resource.
Q200. What is DELETE?
DELETE is used to remove a resource.
Q201. What is JSON?
JSON is a common format used to exchange data between systems.
Example:
{
“customerId”: 101,
“status”: “Active”
}
Q202. What is an HTTP Status Code?
It tells whether an API request succeeded or failed.
Examples:
200 — Success
400 — Bad Request
404 — Not Found
500 — Server Error
Q203. Why should a Business Analyst understand APIs?
A BA may need to understand how systems exchange data and what information is required between them.
Q204. What should a BA document for an integration?
A BA may capture:
Source system
Target system
Data fields
Business rules
Trigger
Expected response
Error cases
Q205. What is system integration?
System integration connects two or more applications so they can share data or work together.
Q206. What is an interface requirement?
An interface requirement explains how one system should interact with another system or user interface.
Q207. What is authentication?
Authentication checks whether a user or system is who it claims to be.
Q208. What is authorization?
Authorization decides what an authenticated user is allowed to access or do.
Q209. Authentication vs Authorization?
Authentication: Who are you?
Authorization: What are you allowed to do?
Q210. What should a Technical BA understand?
A Technical BA should understand enough about:
APIs → Databases → Integrations → Data Flow → System Behavior → Error Handling
The goal is not to become a developer, but to communicate technical requirements clearly.
Practical Scenario
“A payment system needs to connect with an external payment provider. What would you clarify?”
A natural answer:
“I would confirm what data needs to be sent, what response is expected, when the API should be called, how failures are handled, and what should happen after a successful payment.”
Practice Strategy
Take one feature:
Course Payment Integration
Create this flow:
User → Website → Payment API → Payment Provider → Response → Confirmation
Then practise:
- MVP vs Full Product
- Wireframe vs Prototype
- API Request vs Response
- GET vs POST
- Authentication vs Authorization
- Source System vs Target System
Part 8: Advanced Business Analysis, Real-World Scenarios & Case-Based Questions
Advanced BA Questions — 211–240
Q211. What is a business problem statement?
A problem statement clearly explains the issue, who is affected, and why it needs attention.

Solution Assessment checks whether the implemented solution actually meets the business need.
Q215. How do you measure solution success?
Compare expected results with actual results using:
KPIs
User feedback

It checks whether project assumptions are still valid.
Example:
“All users will have internet access.”
Q219. What is a constraint?
A constraint is a limitation affecting the solution.
Examples:
Budget, time, technology, regulation
Q220. Assumption vs Constraint?
Assumption: Something believed to be true.
Constraint: A known limitation.
Q221. What is business value?
Business value is the benefit a requirement or solution provides to the organization or user.
Q222. How do you prioritize when everything is marked urgent?
Compare:
Business value → Risk → Deadline → Dependency → Customer impact
Then involve the right decision-maker.
Q223. What is a requirement conflict?
It happens when two requirements cannot both be satisfied as written.
Q224. How do you resolve requirement conflicts?
Understand both needs, identify the business priority, discuss alternatives, and document the final decision.
Q225. What if stakeholders keep changing requirements?
Track changes formally and show their impact on scope, effort, and timeline.
Q226. What if a stakeholder says, “Build it like the old system”?
Do not copy it immediately.
Understand which old-system features are actually useful and what problem they solve.
Q227. What if users reject a new process?
Find out whether the issue is with the requirement, usability, training, or change adoption.
Q228. What if developers say a requirement is not feasible?
Understand the technical constraint and work with business stakeholders on an acceptable alternative.
Q229. What if QA finds a gap in the requirement?
Review the original requirement, clarify the expected behavior, and update the documentation if needed.
Q230. What if a critical requirement was missed?
Assess the impact, inform stakeholders early, and follow the agreed change process.
Case-Based Questions
Q231. Sales are falling. How would you approach the problem?
Start with:
Data → Customer Segment → Product → Region → Time Period → Root Cause
Avoid jumping directly to a solution.
Q232. Customer complaints suddenly increase. What would you check?
Check:
Complaint category
Recent changes
Customer journey
Support data
Process failures
Q233. A process takes too long. What would you do?
Map the current process and identify:
Waiting Time → Rework → Manual Steps → Approvals → Bottlenecks
Q234. A company wants a new mobile app. What should the BA ask first?
Ask:
Who will use it?
What problem does it solve?
What are the main features?
What is the expected outcome?
Q235. A client wants 20 features in the first release. What would you do?
Prioritize the features and identify the smallest useful first release.
An MVP may be appropriate.
Q236. Two departments want different workflows. How would you handle it?
Understand both processes, identify common steps, document differences, and agree on the required business rules.
Q237. A dashboard shows wrong numbers. What would you check?
Check:
Source Data → Filters → Business Logic → Mapping → Calculations
Q238. An integration is failing. What should a BA verify?
Check:
Expected data
Field mapping
Trigger
API response
Error scenario
Business impact
Q239. Users say the system is difficult to use. What would you do?
Observe how they use it, collect examples, identify unnecessary steps, and discuss possible usability improvements.
Q240. How do you answer an unknown scenario in an interview?
Do not guess immediately.
Use a clear flow:
Understand → Ask Questions → Analyze → Identify Options → Recommend → Validate
Practical Scenario
“A company wants to reduce customer onboarding time from five days to one day. How would you approach it?”
A natural answer:
“I would first map the current onboarding process, measure where time is being spent, identify manual work and approval delays, then discuss possible improvements with stakeholders. After implementation, I would track onboarding time as a KPI.”
Case Interview Approach
For most BA scenarios, use:
Problem → Stakeholders → Current Process → Data → Root Cause → Options → Recommendation → Measure Result
Do not rush to give a solution before understanding the problem.
Practice Strategy
Practise these five situations:
- Conflicting requirements
- Changing requirements
- Process delay
- Wrong dashboard data
- Failed system integration
For each one, explain:
What would you check first?
Who would you speak with?
What would you document?
How would you measure success?
