🏞️ Waterfall Model (Old School)

• Linear & sequential
• Phases: Requirements → Design → Code → Test → Deploy → Maintain
• 💣 No going back once a phase is done
• ✅ Simple but ❌ not flexible
• Best for: Small, fixed-scope projects

⚡ Agile Model (Modern Iterative)

• Iterative & feedback-driven
• Work in sprints (1–2 weeks)
• Continuous: Build → Test → Feedback → Improve
• ✅ Highly flexible, fast delivery
• Best for: Evolving, client-driven projects

🚀 MVP (Minimum Viable Product)

• Basic version of a product
• Just enough features to launch & test
• ✅ Focus: Speed + early feedback
• Fits perfectly into Agile mindset
