Briefly describe the phases in the waterfall model. Requirements gathering: All the requirements are gathered and analysis is performed for the complete system.
Design: Various design models are created for the complete system after the requirements gathering phase has been completed and ended.
Construction: The complete system is constructed once the design for the system has been frozen.
Integration: Various constructed code units are integrated to build the complete system after construction of all units has ended.
Testing: The complete system is tested after all the construction and integration has completed.
Implementation: The complete system is implemented in production after testing has finished.
Maintenance: Post implementation support carries out after implementation of the system.
