9. What is a hybrid model in software development lifecycle?

A hybrid model in software development lifecycle is a combination of one or more models into a single model.

10. What are the two cases of hybrid models in software development?

The two cases of hybrid models in software development are the spiral model with prototype hybrid model and the Vverification and validation model with prototype hybrid model.

11. What is the spiral model with prototype hybrid model?

Spiral model prototype hybrid approach uses a circle diagram for requirements collecting, visibility analysis, design, coding, and testing. A more systematic approach begins with requirement collecting, feasibility analysis, prototype design and development, and testing in the prototype model. If testing finds faults, the developer will fix them and provide the test engineer an updated prototype model.

12. What happens if the customer is not satisfied with the prototype model in the spiral with prototype hybrid model?

The customer will communicate with the design and development team again. The team will design and develop the prototype again, and the test engineer will conduct the testing again. If there are no effects, the prototype model will be given to the customer for review. If the customer is satisfied, the project manager will proceed with the next phase.

13. What is the hybrid model used for in software development lifecycle?

The hybrid model is used when there are dependencies between modules. This model is particularly useful when the requirements are unclear.

14. What happens in the verification and validation model when a customer receives the CRS from the customer?

The project manager gives the SRS to the Stings Ridge engineers and developers. The system testing phase involves reviewing the SRS against the CRS, writing a system test plan, and testing the prototype.

15. What happens if the customer is not satisfied with the prototype model?

Stings Ridge engineers and developers get the SRS from the project manager. System testing comprises comparing the SRS to the CRS, establishing a test plan, and testing the prototype. If the client is unhappy, they will redesign and create the program again, and Stings Ridge will update the SRS versus the CRS.

16. What happens if no defects are found in the prototype model after the system testing phase?

The first customer review will get the prototype. If they agree, the high-level design is ready. Once complete, the project manager will submit the model to Stinging Ridge for development. Stinging Ridge will create integration test plans, cases, and SRS reviews. A low-level design will be created and sent to the Stinging Ridge and developer by the project manager.

17. How does the high-level design phase work in the spiral with prototype hybrid model?

Stings Ridge engineers and developers get the SRS from the project manager. System testing comprises comparing the SRS to the CRS, establishing a test plan, and testing the prototype. If the client is unhappy, they will redesign and create the program again, and Stings Ridge will update the SRS versus the CRS.

18. How does the low-level design phase work in the spiral with prototype hybrid model?

Once the model is ready, the project manager will send it to Stinging Ridge for development. Stinging Ridge will write integration test plans, test cases, and review against SRS. The low-level design will be converted into a low-level design, and the project manager will provide it to the Stinging Ridge and developer.
