A method for referencing time-related entries in different files in a
planning program for project planning, and for determining and optically
reproducing any time delays in the project implementation, with one or
more nominal planning entries, which define times or time intervals, being
entered in a reference file, until which or within which one or more
individual projects are intended to be implemented, with actual entries,
which are a measure of the time evolution of the respective individual
project implementation, being entered in one or more further
individual-project-related files, with the nominal planning entries being
used as time reference data, with respect to which the actual entries of
one or more individual projects are referenced, and with a time overrun
which results or can be predicted on the basis of the actual entries in
comparison with the nominal planning entries, of the respective reference
nominal planning entry being determined by computation and being
reproduced on a display device.
