CASE STUDY;Straight file conversion This method requires that the new system files be created moments before the planned change over. It is important to note that it is only suitable for small size files. Otherwise, it may delay the system implementation plan. The actual data or real data would be used instead of dummy data. This implies that once created, files are already in the form suitable for the new system. Dummy file conversion It requires that files be created long before the planned changeover. Dummy records are used, which are replaced with the actual records immediately before change over. The method is ideal when dealing with large volumes of transaction files or master files. It enables file creation activities to be spread over a long period of time Phased file conversion It requires that the files be converted on a bit-by-bit phases. This implies that instead of changing, for example, a whole department file, the file is changed on a section-by-section basis. It may suitably be applicable on a phased change over method. System change-over Involves changing or switching from existing system to the new developed system.
