Study Notes
System Analysis & Design
- Presented by Menna Ibrahim Gabr
Chapter 5 Part 2: Requirements Determination
- Requirements Gathering:
- A process used to build political support for a project.
- Establishes trust and rapport between the project team and users who will use the system.
- Ensures all key stakeholders (those who influence or are affected by the system) are included.
- Stakeholders might include managers, employees, staff, and customers/suppliers.
- Lack of involvement can cause problems during implementation.
Requirements Gathering Techniques
- Techniques used to gather requirements for a system.
- Key techniques:
- Interviews, JAD sessions (a specialized group meeting), questionnaires, document analysis, and observation.
- Combinations of these techniques are often employed, typically interviews, JAD sessions and document analysis.
Requirements Gathering Techniques - Interviews
- Interviews are extensively used.
- One-on-one or group interviews, depending on time.
- Five steps to the interview process: selecting interviewees, designing questions, preparing for the interview, conducting the interview and follow-up.
- Selecting interviewees involves scheduling based on needs for interview.
- Different perspectives are important.
- People at different organizational levels have different perspectives.
- Staff who perform tasks and managers who oversee tasks both should be interviewed.
- Interview needs may change over time.
Requirements Gathering Techniques - Interviews: Question Design
- Three question types:
- Closed-ended: require explicit answers (multiple choice, arithmetic).
- Open-ended: allow for extended responses (essay format questions).
- Probing: follow-up questions to clarify or gain more information.
- Closed-ended questions are useful when specific, precise information is needed.
- Closed-ended questions do not uncover reasons behind answers nor additional information not initially considered.
- Open-ended questions allow for rich information and provide more control to the interviewee.
- Probing questions follow-up on discussions to gain more understanding or details.
Requirements Gathering Techniques - Interviews: Interview Process
- Crucial to build rapport with the interviewee to encourage complete, honest answers.
- Explain the reason for the interview, and then utilize planned questions.
- Record all provided information meticulously. Irrelevant information could prove useful later.
- Understand the context (the "why") of interviewee inputs.
- If unsure of an answer, ask the question and record how to deal with issue(s)
- Periodically summarizing answers aids in understanding and demonstrates active listening.
Requirements Gathering Techniques - Interviews: Interview Structure
- Organize questions for a logical flow: top-down or bottom-up approaches.
- Top-down approach: Starts with broad issues to more specific.
- Bottom-up approach: Starts with specific to general questions.
- Analysts commonly combine approaches.
Requirements Gathering Techniques - Interviews: Interview preparation
- Prepare for interview like a presentation.
- Construct a detailed plan for interview process and anticipated answers (including follow-ups).
- Verify the sources of information for interviewee's knowledge
- Review all topics, questions, and schedules, addressing urgency if there are time constraints.
Requirements Gathering Techniques - Interviews: Additional notes
- No single question type is superior, use a combination.
- Initial interviews can begin with unstructured questions when details are unknown.
- Interviewer should have a general sense of required info but has few close-ended questions to ask.
- These are the most challenging interviews to conduct because they require open-ended questions to gather additional info quickly and accurately.
Joint Application Development (JAD)
- An information-gathering technique allowing team, users, and management to identify system requirements together.
- Developed by IBM originally, often a top choice for requirement gathering.
- Capers Jones claims it reduces scope creep by 50% and prevents vague or specific issues usually created during the SDLC process.
- Structured process where 10-20 users meet under a facilitator skilled in JAD techniques who guides the discussion but does not participate.
- Facilitator is an expert in both techniques and systems analysis.
- One or two scribes record notes (likely with technology support now).
- Meeting room is usually in a U-shape, with visual aids to help discuss ideas and facilitate the process.
Joint Application Development (JAD): The Meeting
- Group will meet until necessary requirements are gathered.
- Meeting rooms are specially designed (away from offices to avoid distractions).
- The room will have tools for visuals (whiteboard, flip chart, projector).
Joint Application Development (JAD): Group Dynamics
- JAD can suffer from traditional group issues: reluctance to challenge others (especially bosses), certain people dominating discussions, and limited participation from others.
- Electronic JAD (e-JAD) uses software to bypass this problem; ideas are provided anonymously (using groupware).
- This technique can reduce time required for JAD sessions, often by 50-80%.
Joint Application Development (JAD): Additional Points
- Participant selection follows interview process procedures, incorporating diversity of organizational levels and required expertise.
- Availability from work for meetings can be a barrier to participation. Ideally, the participants are the best for the particular business.
- JAD sessions can last from a half-day to several weeks.
- E-JAD sessions are usually one-week periods.
Joint Application Development (JAD): Developing Requirements
- JAD sessions are designed with planned questions to extract specific information.
- Closed-ended questions are not typically used (it is more productive and reveals more to proceed top down).
Joint Application Development (JAD): Preparation
- Preparation for JAD involves planning and familiarizing participants with system-related documentation.
Joint Application Development (JAD): Follow up
- Post-session report is created and circulated to attendees. (similar to interview process).
- Longer sessions to acquire more details mean more time (often a week or 2) for generating a report with a completed review of the data gathered.
Joint Application Development (JAD): Facilitator Roles
- Expert in JAD techniques and has experience with the business in discussion.
- Be neutral and not present personal opinions.
- Facilitate the group when disagreements or deviations occur.
- Facilitate when deviations from agenda lead to new direction needing to be developed.
Joint Application Development (JAD): Facilitation
- Help the group in clarifying technical terms.
- The facilitator should recognize key issues from the discussion for the process (not provide solution).
- Participants understand their roles and provide information and don't need to be formally trained in the analysis process.
