The RECAST Method for Reverse Engineering
RECAST is an acronym for Reverse Engineering into CASE Technology. This is in effect a mini-method, intended to become a public domain standard like SSADM to which it closely adheres, since it is a method for reverse engineering COBOL legacy systems to SSADM logical specifications. It is most of use to those who are considering a method to upgrade or maintain software that is in need of substantial remedial action to improve its maintainability or run on an upgraded or different hardware/software platform.
