Software Engineering basics - Feature-Driven Development (FDD)

Feature-Driven Development (FDD) is an Agile software development methodology that focuses on designing and building software based on small, client-valued features. Each feature represents a specific functionality that can be designed, built, and delivered in a short time.

In simple terms, FDD means developing software feature by feature, ensuring regular and visible progress.

Key Characteristics of FDD

  • Feature-centric development

  • Strong emphasis on domain modeling

  • Iterative and incremental process

  • Short development cycles

  • Clear ownership of features

Five Processes of FDD

  1. Develop an Overall Model
    Understand the system requirements and create a high-level domain model.

  2. Build a Feature List
    Identify and list all features required by the client.

  3. Plan by Feature
    Prioritize features and assign them to development teams.

  4. Design by Feature
    Create detailed designs for selected features.

  5. Build by Feature
    Implement, test, and deliver features incrementally.

Advantages of FDD

  • Clear progress tracking

  • Faster delivery of working features

  • Suitable for large teams

  • High focus on quality and design

  • Improves customer satisfaction

Limitations of FDD

  • Requires experienced developers

  • Less suitable for small projects

  • Depends heavily on accurate domain modeling

Conclusion

Feature-Driven Development emphasizes building software in small, manageable features, ensuring high quality and predictable delivery. It is effective for large and complex software projects with well-defined requirements.
