Agile & Scrum Revision Sheet

1. 📌 Essentials

• Agile methodology emphasizes flexibility collaboration, and iterative development.
• Scrum is a framework within Agile focusing on roles, artifacts, and events.
• Key roles: Product Owner, Scrum Master, Development Team.
• Main artifacts: Product Backlog, Sprint Backlog, Burndown Chart.
• Critical events: Daily Scrum, Sprint Planning, Sprint Review, Retrospective.
• Prioritizes individuals/interactions over tools/processes.
• Sprint duration typically 2-4 weeks.
• The Scrum Master acts as a facilitator, not a manager.
• The Product Owner manages the product vision and backlog.
• The Development Team creates the product increment.

2. 🧩 Key Structures & Components

• Product Backlog — prioritized list of features/functions.
• Sprint Backlog — subset of Product Backlog for current sprint.
• Burndown Chart — visual progress indicator of remaining work.
• Daily Scrum — 15-minute stand-up for synchronization.
• Sprint Planning — sets sprint goal and selects backlog items.
• Sprint Review — inspects the increment and gathers feedback.
• Sprint Retrospective — team reflection to improve processes.
• Roles:
  • Product Owner — defines and prioritizes product features.
  • Scrum Master — facilitates Scrum adherence.
  • Development Team — executes work to build the product.

3. 🔬 Functions, Mechanisms & Relationships

• Product Owner prioritizes backlog items based on value.
• Sprint Planning pulls high-priority items into Sprint Backlog.
• Development Team works on Sprint Backlog tasks during the sprint.
• Daily Scrum ensures team synchronization and identifies obstacles.
• Burndown Chart tracks remaining work, updating daily.
• Sprint Review gathers stakeholder feedback on the increment.
• Retrospective identifies improvements for future sprints.
• Roles collaborate to ensure transparency, inspection, and adaptation.
• Flow:

  Product Backlog
       ↓ (prioritized)
  Sprint Planning
       ↓
  Sprint Backlog
       ↓ (work)
  Daily Scrum → Progress updates
       ↓
  Sprint Review → Feedback
       ↓
  Retrospective → Process improvements

6. ⚠️ High-Yield Pitfalls & Confusions

• Confusing Scrum Master with a project manager; Scrum Master is a facilitator.
• Overlooking the iterative nature; each sprint produces a potentially shippable product.
• Misunderstanding the role of the Product Owner as a decision-maker, not a manager.
• Assuming the Sprint Backlog is static; it evolves during the sprint.
• Confusing the purpose of the Retrospective with Sprint Review.
• Believing the Daily Scrum is a problem-solving meeting; it's for synchronization.
• Ignoring the importance of the Burndown Chart as a progress tool.
• Thinking Scrum prescribes detailed documentation; it values working software.

7. ✅ Final Exam Checklist

• Understand Agile principles: individuals/interactions, adaptation.
