- 5. INTRODUCTION •The Incremental Model is a software development approach where the product is designed, implemented, and tested in increments or builds. •Each increment adds functionality to the previous one until the complete system is developed.
- 6. Characteristics • 1. Iterative: Multiple iterations of development, testing, and refinement. • 2. Incremental: Small increments of functionality are added in each iteration. • 3. Flexible: Requirements can change between increments.
- 7. Phases • 1. Planning • 2. Requirements gathering • 3. Analysis4. Design • 5. Implementation • 6. Testing and evaluation
- 8. TYPES: • Staged Delivery Model • Parallel Development Model
- 9. Staged Delivery Model • The Staged Delivery Model, also known as "incremental implementation, "builds software in successively refined stages: • Team develops one section or function of the project at a time. • Each subsystem builds upon the previous one. • Key advantages: • Enables developers to focus on individual functions. • Provides customers with a detailed view of each function. • Encourages active feedback from stakeholders.
- 10. Parallel Development Model • The Parallel Development Model allows for concurrent development of multiple subsystems: • Different parts of the system are built simultaneously. • The approach can significantly reduce overall development time. • Still, building different subsystems concurrently requires sufficient amount of resources. • Key advantages: • Potential for faster time-to-market delivery. • Allows for simultaneous progress on multiple project components.
- 11. Advantages 1. Early delivery: Initial increments can be delivered quickly. 2. Flexibility: Accommodates changing requirements. 3. Reduced risk: Errors are identified and corrected early.
- 12. Disadvantages •Increased Complexity •Higher Cost •Lack of clear requirements: Can lead to project scope creep. • Dependence on previous increments: Errors can cascade. •More time spent on testing
- 13. Limitations •1. Difficult to predict final product. •It takes a lot of time and effort to fix an issue in one unit if it needs to be corrected in all the units. •A good team and proper planned execution are required.
- 15. Evolutionary Model Types of Evolutionary Models • 1. Prototyping Model • 2. Spiral Model
- 16. CONTENT : • Types of Evolutionary Models? • What is Evolutionary Models?
- 17. Introduction • The Evolutionary Model is a combination of Iterative and Incremental Model
- 18. Iterative and Incremental Model
- 20. When to use Evolutionary Process Model? • When customer wants to start using core features instead of waiting for full software • It is used in large projects because of step by step development • When customer requirements are not fixed.
- 21. Phases 1. PROBLEM DEFINITION 2. PROTOTYPE DEVELOPMENT 3. USER FEEDBACK 4. REFINEMENT
- 22. Advantages 1. Improved accuracy: User feedback improves system accuracy. 2. Flexibility: Accommodates changing requirements. 3. Errors are detected much earlier. 4. Gives quick user feedback for better solutions.
- 23. Disadvantages 1. Time-consuming: Multiple iterations can be time- consuming. 2. Resource-intensive: Requires significant resources. 3.It is slow process because it takes more time for development.
- 24. Limitations • 1. Difficult to predict final product.
