9 System Implementation

SYSTEM IMPLEMENTATION

The purpose of implementation is to build a properly working system, install it in the organization, replace old systems and work methods, finalize system and user documentation, train users, and prepare support systems to assist users. Implementation also involves close-down of the project, including evaluating personnel, reassignment staff, assessing the success of the project, and turning all resources over to those who will support and maintain the system. Six major activities constitute the system implementation phase: Coding, Testing, Installation, Documentation, Training and Support The purpose of these activities is to convert the physical system specifications into working and reliable software and hardware, document the work that has been done, and provide help for current and future users and caretakers of the system.

Coding: Physical design specifications are turned into working computer code Testing: Once coding has begun, the testing process can begin and proceed in parallel. As each program module is produced, it can be tested individually, then as part of a larger program, and then as part of a larger system. Installation: It is the process during which the current system is replaced by the new system. Deliverables: Activity Coding Deliverable Code Program Documentation Testing Test scenarios (test plan) and Test Data Results of program and system testing Installation User guides User training plans Installation and conversion plan Documentation System documentation User documentation Training Classes, Tutorials Training materials, Computer-based training aids Support Help desk Online help Bulletin boards and other support mechanisms

Testing

The purpose of testing is confirming that the system satisfies requirements. Testing software begins earlier in the Systems Development Life Cycle, even though many of the actual testing activities are carried out during implementation. During...
