So what we need to know is another phases rather than the classic phases. It is new methodology for the system development process. The Fast phases is organized by eight phases. The classic phases are of four in number. But the thing is that the FAST phases is detailed organized for the. Every phases in classic approach is broken in two or three further sub phases. The sub phases that are defined in the FAST are given as below:
- Scope definition
- Problem Analysis
- Requirement analysis
- Logical design
- Decision analysis
- Physical design and integration
- Construction and testing
- Installation and delivery
As in all the phases the documentation is necessary for each phases. Once the system is ready, installed and ready for the operation, it is not necessary that the system is bug free. It should be always realized that the system cannot be totally bug free. Maintenance should be frequently done for such systems. Another thing is that the proper documentation be done so that the end user can be able to operate the system easily. If possible training should be done for the end user. Also further upgrade must be done which helps to add the new feature to the system and remove the existing errors.
