3. Waterfall model The Waterfall Model is a linear sequential approach where testing is typically performed after the development phase is completed. Each phase, including requirements gathering, design, development, testing, and deployment, is completed before moving on to the next phase

4. Waterfall model Advantages Disadvantages Not flexible, changes are difficult to implement Testing is done at the end of the development process, so defects are found late Not suitable for complex projects Simple understand Well-defined and structured process Easy to track progress and easy to

5. Requirement gathering acceptance testing V-model system testing system analysis The V-model is a variation of the waterfall model, It emphasizes the relationship between each phase of the development process and its corresponding testing phase. The testing activities are planned in parallel with each development phase, enabling early test planning and higher test coverage. architecture design integration testing unit design unit testing coding

6. V-model Disadvantages Advantages Combines the advantages of the waterfall model and the iterative model Testing is done throughout the development process, so defects are found early Well-suited for projects Can be more complex to manage than other models Requires a high level of communication and coordination between developers and testers complex

7. Planning Iterative model Design Implementation The Iterative Model involves repetitive cycles of development and testing. Each iteration includes requirements gathering, design, development, and testing activities. Feedback from each iteration is used to refine subsequent progressive refinement of the software. Testing Evaluation iterations, enabling Feedback and Refinement Repeat

8. Iterative model Disadvantages Advantages Early delivery of working software reduce risk by identifying and addressing defects early in the development process. Increased satisfaction can be more costly than other models Can be more complex to manage. Can be difficult to estimate the final cost and time of the project. customer

9. 4. Evaluation 1. Planning Spiral model The Spiral Model combines elements of both waterfall and iterative models. It emphasizes risk management multiple iterations. Each iteration includes planning, risk analysis, engineering, and evaluation phases. The model allows for continuous refinement of the software while managing potential risks. through 3. Engineering 2. Risk Analysis

10. Spiral model Disadvantages Advantages Combines the advantages of the waterfall iterative model, incremental model Risks are assessed mitigated throughout development process Well-suited for projects with high levels of uncertainty Can be more complex to manage than other models Requires a high level of communication coordination developers and testers model, and the the and and the between complex

11. Agile model Agile testing models, such as Scrum or Kanban, are iterative development approaches. Testing is an integral part of each iteration or sprint, and testing activities are conducted concurrently with development. Agile models emphasize frequent communication, collaboration, and adaptive planning. and incremental

12. Agile model Disadvantages Advantages Flexible and adaptable to change Frequent delivery of working software High level involvement Can be difficult to manage Requires a high level of technical skill from the team Not suitable for all projects of customer
