    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)
