HISTORY OF THE SOFTWARE
CRISIS was presented in 1986 by Mario Ordaz Schroeder who is the main author of any version of CRISIS. The first version of CRISIS was a command line application developed in Fortran. Subsequent versions were developed in Visual Basic and included a graphical user interface. In 2017 professor Ordaz decided to continue the development and support of CRISIS through his company ERN, rebranding it as R-CRISIS; the table below summarizes the main releases.
