What is a Business Requirements Document (BRD) and when do you use one?

A BRD is a structured document capturing what a business needs a system or change to do, written before technical design begins — used at project initiation to align stakeholders on scope before architecture decisions are made.

What is the difference between functional and non-functional requirements?

Functional requirements describe what the system must do (specific behaviors and features); non-functional requirements describe how well it must do it (performance, security, availability, usability).

What is the difference between AI, Machine Learning, Deep Learning, and Generative AI?

Artificial Intelligence (AI) is the broad field of creating systems that perform tasks requiring human-like intelligence. Machine Learning (ML) is a subset of AI that learns from data, Deep Learning (DL) is a subset of ML that uses neural networks with multiple layers, and Generative AI focuses on creating new content such as text, images, code, or audio based on patterns learned from data.

Why is data quality critical in AI solutions?

Data quality is critical in AI solutions because AI models learn directly from the data they are trained on. If the data is inaccurate, incomplete, inconsistent, or biased, the AI system will produce unreliable results and potentially make poor business decisions. High-quality data improves model accuracy, trustworthiness, and overall business value.

How would you gather requirements for an AI recommendation engine in an ecommerce company?

For an AI recommendation engine, I would first clarify the business goals, such as increasing revenue, improving conversion rates, boosting average order value, or enhancing customer engagement. I would then identify stakeholder needs, required data sources, recommendation use cases, success metrics, and operational constraints to ensure the solution delivers measurable business value.

What is prompt engineering?

Prompt engineering is the practice of designing and refining instructions given to AI systems to produce accurate, relevant, and useful outputs. For Business Analysts, it involves structuring prompts with clear context, objectives, constraints, and expected formats so AI tools can support requirements analysis, documentation, research, and decision-making effectively.

What is vector search?

Vector search is a technique used to find information based on meaning and similarity rather than exact keyword matches. It converts content into numerical representations called vectors and identifies the closest matches based on semantic relationships, making it especially valuable for AI-powered search, recommendations, and knowledge retrieval systems.

What risks do AI systems introduce?

AI systems introduce risks related to data quality, bias, privacy, security, compliance, transparency, and reliability. A Business Analyst should identify these risks early, assess their potential impact on stakeholders and business objectives, and ensure appropriate controls, governance, and monitoring mechanisms are in place.

Your company receives 50,000 support tickets per month and management wants an AI customer support bot. What questions would you ask first, how would you assess feasibility, what stakeholders would you involve, what KPIs would define success, and what risks would you identify?

I would begin by understanding the business problem, current support processes, ticket types, and expected outcomes. I would then assess whether sufficient data, technology, and operational readiness exist to support an AI solution while defining measurable success metrics and identifying key risks and stakeholders.

Can you explain Retrieval-Augmented Generation (RAG)?

Retrieval-Augmented Generation (RAG) is an AI architecture that combines a large language model with an external knowledge source. Instead of relying only on its training data, the model retrieves relevant information at query time and uses that context to generate more accurate, current, and trustworthy responses.

How would you handle a conflict between stakeholders with competing priorities, such as a sales team wanting rapid AI deployment and a compliance team requiring maximum accuracy?

I would focus on understanding the underlying business objectives behind each stakeholder's position and facilitate a collaborative discussion based on facts, risks, and measurable outcomes. Rather than choosing one side, I would help the group evaluate trade-offs and agree on a solution that balances business value, risk, and implementation feasibility.

How is BA work different in AI projects compared to traditional software projects?

Business Analysts in AI projects spend more time defining business outcomes, data requirements, model behavior expectations, and evaluation criteria than detailed deterministic system rules. Unlike traditional software, AI solutions are probabilistic, meaning BAs must help stakeholders understand uncertainty, bias, accuracy trade-offs, and ongoing model monitoring.

How would you explain hallucination to a business stakeholder?

I would explain hallucination as a situation where an AI system generates information that sounds convincing but is incorrect, fabricated, or unsupported by real data. Business stakeholders should understand that AI can produce confident-sounding answers even when it lacks reliable information, which is why validation and human oversight remain essential.

How would you handle a situation where an AI chatbot is providing incorrect answers and customers are complaining?

I would start by identifying the scope and impact of the hallucination issue, then analyze chatbot interactions, training data, prompts, and system behavior to determine the root cause. I would collaborate with product, engineering, AI, support, and compliance teams to implement corrective actions that improve response accuracy while reducing customer impact.

A CEO says, "Let's implement AI." How would you respond, identify the real business problem, and determine whether AI is actually necessary?

I would avoid jumping directly to a solution and instead focus on understanding the business objective behind the request. Using structured discovery techniques, I would identify the underlying problem, desired outcomes, success metrics, and constraints before evaluating whether AI, automation, process improvements, or another solution is the most appropriate option.

An AI assistant has been launched, but only 10% of employees are using it. How would you investigate the issue, what metrics would you analyze, what stakeholder interviews would you conduct, and what recommendations would you provide?

I would treat low adoption as a business problem requiring both quantitative and qualitative analysis. I would examine usage data, identify barriers to adoption through stakeholder interviews, and determine whether the root causes relate to awareness, usability, trust, training, process fit, or perceived value before recommending targeted improvements.

What is the role of a Business Analyst in an AI product company?

A Business Analyst in an AI product company bridges business objectives, user needs, and technical AI capabilities. They help define problems worth solving, gather and prioritize requirements, align stakeholders, and ensure AI solutions deliver measurable business value while remaining feasible, ethical, and compliant.

What are embeddings?

Embeddings are numerical representations of data such as text, images, or documents that capture their meaning and relationships in a machine-readable format. They allow AI systems to compare similarity, perform semantic search, make recommendations, and understand context beyond exact keyword matching.

What deliverables have you created as a BA?

Business Analysts create deliverables that help define, communicate, and validate business needs and solution requirements. Common examples include business requirements documents, functional requirements, process maps, user stories, use cases, stakeholder analyses, and requirements traceability matrices. The specific deliverables depend on the project methodology, stakeholders, and organizational standards.

What is an LLM?

An LLM, or Large Language Model, is an artificial intelligence model trained on vast amounts of text data to understand and generate human-like language. Business Analysts increasingly use LLMs to accelerate research, documentation, requirements analysis, stakeholder communication, and knowledge discovery while still applying human judgment and validation.
