Detailed explanation-1: –The above statement is true. In incremental model, requirements do not need to be prioritized.-Requirements of the complete system are clearly defined and understood.-In this model, major requirements must be defined, however some functionalities or requested enhancements may evolve with time.
Detailed explanation-2: -The incremental model prioritizes the requirements of the system and then implements them in groups. Each subsequent release of the system adds function to the previous version until all designed functionality has been implemented.
Detailed explanation-3: -As part of the Incremental model, each module (increment) passes through four phases: requirements, design and development, testing, and implementation.
Detailed explanation-4: -Advantages of Incremental model: Generates working software quickly and early during the software life cycle. This model is more flexible – less costly to change scope and requirements. It is easier to test and debug during a smaller iteration. In this model customer can respond to each built.
