Answer to Question 1

The traditional SDLC breaks the system development process into five separate phases or stages. In the first investigation phase, the system feasibility is determined and a report is produced on this. This leads to a detailed analysis of the existing system and a determination of what the future system should be able to do in the second, analysis phase. The output from this phase has to be converted into a set of detailed design specifications in the design phase. The hardware and software are acquired and customized in the implementation phase, and then the systems are maintained in the maintenance phase. This includes ongoing training and system upgrades and debugging.

Answer to Question 2

A
