Study Notes
SDLC Phases
- The final product of the design phase is the physical system specifications, ready to be turned over to programmers and other system builders for construction.
Design Phase
- Logical design vs physical design: physical design focuses on the physical components of the system, while logical design focuses on the system's functionality and behavior.
Implementation Phase
- Detailed design specifications are turned over to programmers as the first part of the implementation phase.
- During this phase, analysts turn system specifications into a working system that is tested and then put into use.
- Implementation is usually the longest and most expensive part of the process.
- Implementation activities include:
- Coding: programmers write the programs that make up the system.
- Testing: programmers and analysts test individual programs and the entire system to find and correct errors.
- Installation: the new system becomes part of the daily activities of the organization, and application software is installed or loaded on existing or new hardware.
- Initial user support: finalization of documentation, training programs, and ongoing assistance.
Maintenance Phase
- When a system is operating in an organization, users sometimes find problems with how it works and often think of better ways to perform its functions.
- In maintenance, programmers make changes that users ask for and modify the system to reflect changing business conditions.
- These changes are necessary to keep the system running and useful.
- Major types of maintenance include:
- Corrective Maintenance: fixing errors/faults/defects that are observed when the software is in use.
- Preventive Maintenance: implementing changes to prevent the occurrence of errors.
- Adaptive Maintenance: changing the software to make it adaptable to new environments.
- Perfective Maintenance: changing the software to add new functionalities.
SDLC Outputs/Deliverables
- Physical system specifications (design phase)
- Working system (implementation phase)
- Ongoing support and maintenance (maintenance phase)
