The problems of transferring software: a medical case history.

This paper discusses the problems which arose in the transfer of a Pathology Laboratory data-base system from a CTL Mod 1 computer to a Ferranti Argus 700E computer. Both systems were programmed in CORAL-66. Definition of the analytical tests, the wards and clinics and G.P.'s addresses serviced by the laboratory proved to be a much larger task than had been anticipated. The mirroring of the comparative facilities of the two hardware systems is also described.
