In many cases the large, critical production systems referred to as ‘legacy’ are well-planned, well-managed, growing systems. In other cases, the ‘legacy’ now exists in an almost exclusively physical form (that is, a large corpus of program code and application data) frequently with inadequate or absent user and technical documentation. In the worst case, only run-time components may remain after the loss of source code. In addition, as organizations mature, diminishing numbers of technical personnel with direct knowledge of the application’s internals remain on staff. Organizations have responded to the rapid rate of technological advances in desktop computing and graphical user interfaces by adding services using newer technologies while retaining legacy applicaMany organizations rely on legacy applications hosted on mainframe computer
