Study Notes
Incremental Model
- Enables gradual development by adding functionality incrementally.
- Key advantages include:
- Early versions allow for earlier market release.
- Greater flexibility in accommodating changes.
- Simpler testing processes compared to full system development.
- Reduces unnecessary features, enhancing user satisfaction.
- Notable disadvantages include:
- Requires thorough planning and design.
- Needs clear and comprehensive definitions.
- Typically incurs higher costs than traditional waterfall models.
- Usage includes scenarios with:
- Clearly defined major requirements.
- Needs for quick market entry.
- Implementation of new technologies.
- Limited availability of skilled personnel.
Iterative Model
- Developed through repeated cycles that refine previous iterations.
- Key advantages include:
- Identification of requirements through ongoing feedback.
- Reduction of risks via early problem detection.
- Flexibility to redesign and rework based on findings.
- Disadvantages include:
- Potentially rigid process leading to overlapping efforts.
- Can become costly due to repeated development cycles.
- Suitable for projects with:
- Evolving requirements that may change over time.
- Necessity of user feedback to guide development.
- Complex projects where iterative testing improves outcomes.
- Risk management needs to address issues early.
Scrum Framework Activities
- Inputs include:
- Product backlog, team capacity, and past performance metrics.
- Daily Scrum Meetings focus on:
- Activities completed yesterday.
- Plans for today.
- Any identified obstacles.
- Sprint Review involves demonstrating completed features to gather client feedback.
- Sprint Retrospective allows the team to discuss improvements after each sprint.
Artifacts of Scrum
- Product Backlog: Prioritized list of features, including user stories, changes, and bug fixes.
- Sprint Backlog: Specific features and stories planned for the current sprint, taken from the product backlog.
Alignment with Agile Manifesto
- Prioritizes:
- Individuals and interactions over strict adherence to processes.
- Delivering working software rather than extensive documentation.
- Customer collaboration over traditional contract negotiations.
- Adaptability to change rather than rigidly following a plan.
- Emphasizes simplicity in planning and process execution.
Extreme Programming (XP)
- Aims to deliver high-priority user stories as tested software in frequent iterations.
- Focuses on working software, continuous feedback, and flexibility.
Properties of Requirements
- Requirements should be:
- Clear, concise, consistent, unambiguous, feasible, traceable, verifiable, prioritized, and quantifiable.
Feasibility Study Purpose
- Conducted before project initiation to evaluate practicality.
- Considerations include stakeholder involvement, current solutions, target market analysis, potential benefits, and budget requirements.
Requirements Engineering Process
- Step 1: Elicit requirements by collaborating with stakeholders to clarify their needs and project scope.
- Ensure documentation characteristics include accuracy, appropriateness for the audience, online maintenance, and professionalism.
Requirements Validation & Verification
- Important to check:
- If software requirements address the right problems (validation).
- If they are correctly specified (verification).
Prototyping Definition
- Encourages user involvement and ensures mutual understanding between users and engineers.
- Most effective in projects with significant user interactions.
Requirements Change Management
- Emphasizes controlled changes to avoid costly impacts on project aspects.
- A formal process includes logging change requests, performing impact analysis, and obtaining stakeholder approval.
