Today, we're going to discuss one of the most foundational techniques for requirement elicitation: interviews. Can someone tell me what an interview is?
It's a conversation with stakeholders to gather information.
Exactly! There are different types of interviews: structured, unstructured, and semi-structured. Can anyone describe the difference?
Structured has a set list of questions, while unstructured is more free-flowing, right?
Correct! The semi-structured format is a blend of both. When would you think we should use interviews?
When we need in-depth insights, especially from a small number of stakeholders.
Right! And while they provide rich information, they can also be time-consuming. Always prepare thoroughly for interviews!

Chapter Content
Requirement Elicitation is the process of gathering requirements from stakeholders and subject matter experts (SMEs) to understand what the business truly needs. This step is critical for project success, as poorly gathered or misunderstood requirements can lead to product failure.
Detailed Explanation
Requirement elicitation is essentially the practice of collecting information from people who have a stake in a project. These individuals, known as stakeholders, can include end-users, customers, and experts with specific knowledge. The goal is to accurately understand what is needed from a project to ensure that the developers, designers, and business analysts all have a clear set of requirements to work from. If these requirements are not carefully gathered and understood, there's a risk that the final product will not meet the necessary standards or needs, possibly leading to project failure.
Examples & Analogies
Think of requirement elicitation like gathering ingredients for a recipe. If you donβt list the correct ingredients, or if you misunderstand the quantities, the final dish could turn out badly or even be inedible. Just as a successful dish depends on exact measurements and details, a successful project depends on accurate requirements.

Interviews
Definition: A face-to-face or virtual conversation with stakeholders to gather insights, expectations, and needs.
Types:
- Structured: Pre-defined set of questions
- Unstructured: Open-ended, free-flowing
- Semi-structured: A combination of both
When to Use:
- When you need in-depth insights
- When stakeholders are few in number and available
Advantages:
- Rich, detailed information
- Personalized interaction helps clarify requirements
Disadvantages:
- Time-consuming
- May result in bias if not done carefully
Example Questions:
- What are the current challenges you face?
- What features would make your job easier?
BA Tips:
- Prepare thoroughly
- Ask open-ended questions
- Record and document responses accurately
Detailed Explanation
Interviews are a vital technique for requirement elicitation. They involve discussions either face-to-face or virtual meetings where a business analyst (BA) interacts directly with stakeholders. This allows the BA to gather deep insights into what stakeholders really need. Depending on the goal, interviews can be structured, where questions are predefined, or unstructured, allowing the conversation to flow more naturally. Semi-structured combines both approaches. Interviews are best used when you need comprehensive details and when there are not too many stakeholders to manage. However, they can take significant time and may lead to unintentional bias based on how questions are asked or how the interview is conducted.
Examples & Analogies
Imagine conducting an interview as if you were trying to uncover the backstory of a character in a novel. The more detailed and open-ended your questions are, the richer the story you will uncover. Just like a good author seeks depth in their characters, a BA seeks depth in understanding stakeholder needs.
Surveys and Questionnaires

Surveys and Questionnaires
Definition: A set of predefined questions distributed to a larger group of stakeholders to collect input.
When to Use:
- When stakeholders are geographically dispersed
- When time is limited
- When quantitative data is needed
Advantages:
- Cost-effective
- Collects input from many participants
Disadvantages:
- Limited follow-up and clarification
- Risk of low response rate or vague answers
BA Tips:
- Keep it concise and focused
- Use a mix of closed and open-ended questions
- Pilot test the survey before large distribution
Example Tools:
- Google Forms, SurveyMonkey, Microsoft Forms
Detailed Explanation
Surveys and questionnaires are useful for gathering information from a larger audience efficiently. They involve distributing a standardized set of questions to many stakeholders, making it easier to collect a broad range of opinions and data. This method is especially advantageous when stakeholders are spread across different locations, or when time constraints prevent in-depth interviews. While surveys can be highly cost-effective and gather quantitative data well, they do come with challenges such as the potential for low response rates or vague answers, as participants may not always be able to provide extensive feedback.
Examples & Analogies
Think of a survey as a poll in a classroom where the teacher asks everyone to quietly raise their hands to express their favorite subject. It allows the teacher to quickly gather a lot of data from the entire class, but if the question isnβt well-framed or if a student doesnβt understand it, their response may not accurately reflect their feelings. This highlights the importance of crafting good survey questions.
Observation (Job Shadowing)

Chapter Content
Observation (Job Shadowing)
Definition: Watching stakeholders perform their actual tasks to understand their workflows, tools, challenges, and interactions.
Types:
- Passive Observation: BA silently observes the task
- Active Observation: BA asks questions during the process
When to Use:
- When stakeholders are unable to articulate needs
- When actual usage differs from stated procedures
Advantages:
- Reveals unspoken requirements
- Identifies hidden problems and workarounds
Disadvantages:
- Time-intensive
- May influence user behavior ("Hawthorne Effect")
BA Tips:
- Take detailed notes
- Be respectful and unobtrusive
- Validate observations with the stakeholder afterward
Detailed Explanation
Observation, or job shadowing, is a technique where the BA watches stakeholders execute their tasks in real-time. This helps uncover practical challenges and workflows that may not be captured through interviews or surveys. There are two types of observation: passive and active. Passive observation involves simply watching, while active observation includes asking questions during the task. This method is particularly beneficial when stakeholders struggle to express their needs or when thereβs a discrepancy between documented processes and actual practices. However, it can be time-consuming, and observers should be careful not to influence the behaviors of those being observed.
Examples & Analogies
Think of job shadowing like a behind-the-scenes look at how a film is made. The observer can see all the little details and challenges that go into the production that arenβt obvious in the final cut. This experience can reveal things that arenβt written down, much like how a behind-the-scenes documentary can show the reality of filmmaking.
Workshops
Chapter 5 of 6

Chapter Content
Workshops
Definition: Structured group sessions involving stakeholders and the BA to collaboratively gather, analyze, and validate requirements.
When to Use:
- For complex or cross-functional requirements
- To resolve conflicting viewpoints
Advantages:
- Encourages stakeholder alignment
- Faster than conducting multiple individual interviews
Disadvantages:
- Requires skilled facilitation
- Group dynamics can affect outcomes
Common Workshop Types:
- Requirement Gathering
- Prototyping/Design Workshops
- Prioritization Workshops
BA Tips:
- Prepare an agenda and invite the right mix of participants
- Use visual aids (whiteboards, diagrams)
- Facilitate neutrally and manage time wisely
Detailed Explanation
Workshops are interactive sessions where stakeholders and business analysts come together to collaboratively explore and define requirements. They are particularly useful for tackling complex issues that might involve multiple departments or conflicting opinions. Workshops can foster alignment among stakeholders, allowing for quicker consensus compared to individual interviews. However, they require skilled facilitators to manage discussions and ensure that group dynamics do not lead to dominant voices overpowering others. Further, itβs important to prepare properly for a workshop by having a clear agenda and using visual aids to enhance understanding.
Examples & Analogies
Consider workshops like a team huddle before a big game. During this time, players and coaches discuss strategy, align on objectives, and ensure everyone knows their role. Just as a successful game plan requires input from multiple players, a successful project outcome depends on collective input and consensus from all stakeholders.

Brainstorming
Definition: A group creativity technique used to generate a wide range of ideas in a short time.
When to Use:
- During early stages of solutioning
- When exploring new features or improvements
Advantages:
- Encourages innovation and participation
- Builds team ownership of solutions
Disadvantages:
- Can go off-topic
- Needs facilitation to capture useful ideas
BA Tips:
- Set clear objectives and rules (e.g., no criticism)
- Use sticky notes, mind maps, or online tools
- Follow up with prioritization or voting
Detailed Explanation
Brainstorming is a creative technique aimed at generating a variety of ideas and solutions in a collaborative environment. It is most effective during the early stages of project development when new features or improvements are being considered. During a brainstorming session, all participants are encouraged to contribute any ideas, which fosters creativity and innovation. However, it may be challenging to stay on topic, and effective facilitation is crucial to ensure that useful ideas are captured and that the session remains productive.
Examples & Analogies
Think of brainstorming like a group of chefs coming together for a cook-off. Each chef brings their unique ideas and ingredients to the table. While they share and build off each other's concepts, it's essential for someone to guide the discussion to prevent chaos and ensure that great ideas are distilled into a winning dish. Just as a successful cook-off relies on collaboration, a fruitful brainstorming session relies on the collective creativity of the group.
