SDM 3 - Stages of SDLC (Part 2) Flashcards
What does the development stage marks?
It marks the start of execution of the logical design from the design stage
What do we do in the development stage?
- It involved personnel starts to assemble and install hardware and software components of the system, or execute other projects to build custom software if they were required
- users are trained to operate the new system through a formally designed training program
What is the implementation phase?
It involves converting old system data files to the new system data formats, or known as cutover
What are the ways in cutover?
- Direct cut
- Pilot
- Parallel
- Phased
What is direct cut?
The old system are replaced fully by the new system
What is pilot?
A select group are given access to trial the new system before implementing globally
What is parallel?
Both systems are run simultaneously until the new one is considered stable and usable
What is phased?
Parts of the new system are implemented as seen fit until the new system is fully installed
What happens after implementation?
The system documentation will be finalized
The system documentation will serve as the reference document for maintenance stage
What is evaluation and maintenance?
It ensures the new system is working as intended and allow necessary changes to be made should issues arise
What is the purpose of evaluation and maintenance
- Error correction and fault finding for issues not discovered during development and implementation stage
- System improvement on new systems after user familiarity to the system suggesting efficient approach
Why is maintenance similar to the previous SDLC stage
- Development of more efficient modules, then integrate and test them
- Studying new user requirements on the existing system to react to any changes requested by the organization
- Troubleshooting issues not discovered during testing stage of SDLC and revising system documentation to accommodate new troubleshooting knowledge
