Agile Development

What is Agile Development?

• A style of software development that aims for speed and adaptability
• Instead of spending months designing everything up front...
  → Release early, then improve continuously
• Focus on user feedback, iteration, and value delivery

A good fit for web services, mobile apps, and fast-changing markets

Why Agile?

• Traditional (waterfall) development often:
  • Takes too long
  • Delivers features no one uses
  • Misses market timing
• Agile aims to:
  • Deliver early and often
  • Respond to change
  • Prioritize working software

Agile vs. Non-Agile: The Car Analogy

We want to build a vehicle:

• Non-Agile (Waterfall)
  • Release 1: Tires
  • Release 2: Engine
  • Release 3: Steering wheel
  • ... → Finally, a car (but too late)

No one wants just tires

• Agile
  • Release 1: Skateboard
  • Release 2: Bicycle
  • Release 3: Motorcycle
  • ... → Car (validated step-by-step)

Always deliver something usable

Agile in Practice

• Work is divided into iterations (e.g., 1–2 weeks)
• Each iteration delivers a working product
• Continuous cycle of:
  1. Plan
  2. Build
  3. Test
  4. Review
  5. Improve

Summary

Agile development is a flexible and user-focused approach.
It emphasizes:

• Fast and frequent releases
• Continuous improvement
• Collaboration and customer feedback
• Well-suited for web and mobile products
