What Does a Business Analyst Do?

A business analyst (BA) acts as a translator, communicator, and problem-solver. You work with stakeholders—executives, end-users, and technical teams—to understand business needs, define requirements, and ensure the final solution meets those needs. Your role involves:
  • Gathering Requirements: Eliciting needs through interviews, workshops, or surveys.
  • Documenting Needs: Creating clear, structured documents to guide projects.
  • Facilitating Communication: Ensuring business and technical teams speak the same language.
  • Problem-Solving: Identifying risks, resolving conflicts, and clarifying ambiguities.
  • Validating Solutions: Confirming the delivered product aligns with requirements.

​
Core Documents Every Business Analyst Should Master

Three critical documents form the backbone of a business analyst’s work: the Business Requirements Document (BRD), the Functional Requirements Document (FRD), and the Software Requirements Specification (SRS). Each serves a distinct purpose and audience.

​
1. Business Requirements Document (BRD)

The BRD is your starting point. It captures the high-level business objectives and answers, “What does the business want to achieve?” Key Components:
  • Executive Summary: A concise overview of the project’s purpose.
  • Business Goals & Objectives: Specific, measurable goals (e.g., “Increase sales by 10%”).
  • Scope: What’s included and excluded in the project.
  • Stakeholder Analysis: Who’s involved and their roles.
  • Business Requirements: A detailed list of business needs.
  • Assumptions & Constraints: Factors like budget, timelines, or regulations.
Why It Matters:
  • Aligns stakeholders on the project’s purpose.
  • Acts as a contract between the business and project team.
  • Prevents scope creep by setting clear boundaries.
Tips for Success:
  • Keep it high-level and avoid technical details.
  • Use clear, jargon-free language for non-technical stakeholders.
  • Validate with stakeholders to ensure agreement.

​
2. Functional Requirements Document (FRD)

The FRD dives deeper, translating business needs into specific functionalities. It answers, “How will the system meet these needs?” Key Components:
  • Functional Overview: A summary of what the system will do.
  • Use Cases: Scenarios showing how users interact with the system.
  • System Workflows: Diagrams illustrating data or process flows.
  • Business Rules: Logic or conditions (e.g., “Users must be logged in to access X”).
  • User Interfaces (UI): Mockups or descriptions of screens.
  • Data Requirements: Inputs, outputs, and storage needs.
Why It Matters:
  • Guides developers in building the solution.
  • Ensures the system aligns with business goals.
  • Reduces miscommunication between business and technical teams.
Tips for Success:
  • Be specific but avoid dictating technical solutions.
  • Use visual aids like flowcharts to clarify complex processes.
  • Review with both business and technical stakeholders.

​
3. Software Requirements Specification (SRS)

The SRS is the most comprehensive document, combining functional and non-functional requirements to provide a complete blueprint for development. Key Components:
  • Introduction: An overview of the system.
  • Functional Requirements: Detailed system functions.
  • Non-Functional Requirements: Criteria like performance (e.g., “Load time under 2 seconds”), security, usability, or compliance.
  • External Interfaces: Connections to other systems or APIs.
  • System Architecture: A high-level technical design.
Why It Matters:
  • Covers all aspects of system performance and quality.
  • Serves as a reference for developers and testers.
  • Ensures the solution meets both business and technical standards.
Tips for Success:
  • Be thorough but organized—use templates to stay consistent.
  • Include measurable criteria for non-functional requirements.
  • Collaborate with technical teams to ensure feasibility.

Strategies for Success as a New Business Analyst

To excel in your role, focus on these foundational strategies:
  1. Master Clear Communication
    • Use simple, precise language to avoid confusion.
    • Confirm understanding by summarizing discussions or sharing drafts.
    • Tailor your communication style to your audience (e.g., executives vs. developers).
  2. Build Strong Stakeholder Relationships
    • Identify key stakeholders early and understand their priorities.
    • Actively listen during requirements-gathering sessions.
    • Manage expectations by being transparent about constraints.
  3. Leverage Visual Tools
    • Use diagrams (e.g., flowcharts, wireframes) to make complex ideas accessible.
    • Tools like Lucidchart, Visio, or Miro can enhance clarity.
    • Mockups or prototypes can help stakeholders visualize the solution.
  4. Prevent Scope Creep
    • Define and document the project scope early in the BRD.
    • Use change management processes for new requests.
    • Regularly review requirements with stakeholders to stay aligned.
  5. Support Quality Assurance
    • Use your requirements as a benchmark for testing.
    • Collaborate with QA teams to ensure test cases cover all requirements.
    • Validate the final product against the BRD, FRD, and SRS.
  6. Stay Organized and Detail-Oriented
    • Use templates for consistency across documents.
    • Track changes and versions to avoid confusion.
    • Double-check requirements for clarity and completeness.

​
Common Challenges and How to Overcome Them

  • Ambiguous Requirements: Ask clarifying questions and validate with stakeholders. Use examples or scenarios to pin down details.
  • Conflicting Stakeholder Needs: Facilitate discussions to prioritize requirements. Document trade-offs and decisions.
  • Technical Jargon Overload: Translate technical terms into business-friendly language and vice versa.
  • Time Constraints: Prioritize high-impact requirements and use iterative approaches like Agile to deliver incrementally.

​
Tools to Get You Started

  • Documentation: Microsoft Word, Google Docs, or Confluence for writing BRDs, FRDs, and SRSs.
  • Diagramming: Lucidchart, Microsoft Visio, or Draw.io for workflows and wireframes.
  • Project Management: Jira, Trello, or Asana for tracking tasks and requirements.
  • Prototyping: Figma or Balsamiq for UI mockups.

Final Thoughts

As a business analyst, your ability to translate business needs into actionable requirements is critical to project success. By mastering the BRD, FRD, and SRS, and honing skills like communication, stakeholder management, and problem-solving, you’ll deliver value to your organization and grow in your career. Start small, seek feedback, and continuously refine your approach—every project is a chance to learn and improve.
