Iterative Model
Overview:
- Repetitive Cycles: The Iterative model involves repetitive cycles of prototyping, testing, and refining.
- Phases: Divided into smaller cycles, each containing its own planning, design, implementation, and testing.
- Flexibility: Adaptable to changes even late in the development process.
- Delivery: Delivers a working subset of the product in each iteration.
Characteristics:
- Dynamic Requirements: Suited for projects with evolving or unclear requirements.
- Prototyping: Often involves the creation of prototypes for user feedback and validation.
- Customer Collaboration: Encourages ongoing customer involvement and feedback.
- Progress Tracking: Progress is measured by the completion of iterations.
Suitability:
- Changing Requirements: Ideal for projects with dynamic or changing requirements.
- Continuous Improvement: Emphasizes continuous refinement and improvement.
- Large Projects: Suitable for larger projects where phased delivery is beneficial.
Waterfall vs Iterative SDLC Model
The Waterfall model and the Iterative model are two different software development life cycle (SDLC) approaches, each with its own set of characteristics and principles. Let’s compare the Waterfall model and the Iterative model in terms of their key aspects:
