  • Samuel Kofi Odoi Ghana After the users are trained about the computerized system, working has to shift from manual to computerized working. The process is called Changeover. The following strategies are followed for changeover of the system. Direct Changeover: This is the complete replacement of the old system by the new system. It is a risky approach and requires comprehensive system testing and training. Parallel run : In parallel run both the systems, i.e., computerized and manual, are executed simultaneously for certain defined period. The same data is processed by both the systems. This strategy is less risky but more expensive because of the following facts: Manual results can be compared with the results of the computerized system. The operational work is doubled. Failure of the computerised system at the early stage does not affect the working of the organization, because the manual system continues to work, as it used to do. (iii) Pilot run: In this type of run, the new system is run with the data from one or more of the previous periods for the whole or part of the system. The results are compared with the old system results. It is less expensive and risky than parallel run approach. This strategy builds the confidence and the errors are traced easily without affecting the operations. The documentation of the system is also one of the most important activity in the system development life cycle. This ensures the continuity of the system. Generally following two types of documentations are prepared for any system. User or Operator Documentation System Documentation User Documentation: The user documentation is a complete description of the system from the user’s point of view detailing how to use or operate the system. It also includes the major error messages likely to be encountered by the user. System Documentation: The system documentation contains the details of system design, programs, their coding, system flow, data dictionary, process description, etc. This helps to understand the system and permit changes to be made in the existing system to satisfy new user needs.
