Waterfall Model

This model is the structure approach. It divided into 6 phases that supposed to proceed linearly through the phases of requirement. Output for each phase becomes input of the next process.

Below is the statement for each phase of the Waterfall Model.

phase 1
ANALYSIS

The research on user to develop new specific software.
In this phase, what was done by the new system is defined but not how to executed it.

Phase 2
DESIGN

The level where all the research done is translated into written form. For example: Formation of objective software, elements construction, selection of software presentation strategy and so on..

Phase 3
IMPLEMENTATION

A group of developer will build or generate the design done in previous phase.

Phase 4
DEVELOPMENT

The level of development and integrate software. This is the real process of software producing.

Phase 5
TESTING

Application will be tested and evaluated to ensure that its working correctly, fulfil the design, achieve the objective and so on.

Phase 6
MAINTENANCE

The final phase in Waterfall Model. In this phase, the software will be managed before it use effectively.Next, the modification process will be done to improve the quality of software.
