Phases in the waterfall model - Project management (PMP)

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.
