Requirements Elicitation Tips

  1. Engage with Stakeholders Early and Often

    Identify key stakeholders—such as end-users, product owners, and business analysts—early in the project and build a communication plan to stay engaged with them. Their insights are crucial to understanding needs, priorities, and constraints.

    Failing to engage all relevant stakeholders can lead to incomplete requirements, as important perspectives might be missed.

  2. Ask Open-Ended Questions

    Use open-ended questions to explore what users truly need, rather than what they think they want. For example, instead of asking, “Do you need a report function?” ask, “How would you like to view or analyse your data?”

    Avoid leading questions, as they can bias stakeholders toward specific solutions and result in inaccurate requirements.

  3. Use Multiple Elicitation Techniques

    Combine methods like interviews, workshops, surveys, observations, and brainstorming sessions to gather requirements from various angles. Different methods provide different insights and help build a comprehensive view.

    Relying solely on one technique (e.g., interviews) may limit the quality and breadth of information gathered.

  4. Document Everything Carefully

    Take detailed notes and document all requirements gathered, including assumptions, constraints, and any open questions. Visual aids like use cases or user stories can help make requirements clearer.

    Failing to document requirements thoroughly can lead to misunderstandings and miscommunication later in the project.

  5. Validate Requirements with Stakeholders

    After each elicitation session, confirm your understanding of the requirements with stakeholders. Summarise what was discussed and ask for feedback to ensure accuracy.

    Assuming that you’ve understood requirements without validation can lead to incorrect assumptions, resulting in a product that doesn’t meet user needs.

  6. Focus on the Problem, Not the Solution

    Concentrate on understanding the problem the user is facing rather than jumping to specific solutions. This encourages creativity in finding the best solution during the design phase.

    Prematurely committing to a solution can limit flexibility and lead to a product that might not fully solve the user’s problem.

Requirements Analysis Tips

  1. Organise and Prioritise Requirements

    Categorise requirements into functional, non-functional, and technical requirements. Prioritise them based on factors like business value, feasibility, and dependencies to focus on the most critical features first.

    Treating all requirements as equally important can lead to scope creep and dilute focus on core functionality.

  2. Identify Ambiguities and Clarify Language

    Look for ambiguous terms (e.g., “easy to use,” “fast,” “secure”) in requirements and clarify them with measurable criteria. Clearly defined language prevents misinterpretation during implementation.

    Overlooking vague language can lead to different interpretations of the same requirement among developers, testers, and stakeholders, creating confusion.

  3. Analyse Feasibility and Constraints

    Assess the feasibility of each requirement by considering technical, financial, and time constraints. Involve technical experts to evaluate whether requirements are realistic and achievable.

    Failing to evaluate feasibility may lead to unrealistic commitments or delays later in development if certain requirements prove unachievable.

  4. Manage Dependencies and Conflicts

    Identify dependencies between requirements and address conflicts early. For example, if two requirements depend on different technologies, find ways to harmonise them before development starts.

    Ignoring dependencies or conflicts can cause issues during implementation, as dependent requirements might impact each other’s functionality or performance.

  5. Create Prototypes or Mockups Where Possible

    Use prototypes, wireframes, or mockups to visually represent complex requirements. These tools help stakeholders better understand the requirements and provide more actionable feedback.

    Relying solely on written requirements may lead to misunderstandings, as stakeholders might interpret written descriptions differently.

  6. Establish Acceptance Criteria

    Define clear, measurable acceptance criteria for each requirement to guide developers and testers. Acceptance criteria should describe how the functionality will be evaluated to confirm it meets the requirement.

    Omitting acceptance criteria or leaving them vague can lead to disagreements during testing and sign-off, as stakeholders may have different expectations.

Common Pitfalls to Avoid

  • Scope Creep: Keep a close watch on new or modified requirements that arise during the project. Use a formal change management process to control scope and avoid unnecessary additions that don’t add value.

  • Analysis Paralysis: Requirements analysis should be thorough but time-limited. Spending too much time perfecting requirements without progressing to development can delay the project. Strike a balance between detail and forward momentum.

  • Ignoring Non-Functional Requirements (NFRs): Address performance, usability, scalability, security, and other non-functional requirements early. NFRs can impact system architecture and user experience significantly.

  • Failing to Involve End Users: Involve actual end users, not just business stakeholders, in elicitation and validation. End users often have insights that other stakeholders might overlook.
