The old applications are inflexible. Their adaptation to
changes is difficult, they are dissected vertically, and only
certain areas are automatized, so the data relating to different
areas must be entered separately, which is time- and workconsuming.
It is indispensible to know the exact demand of the
users so that the different levels of management can obtain the
data relevant for them. Asking for the necessary information
does not always give the expected results: giving the aggregated
data takes too long because the proper links are missing from
the databases A further fault of this management information
system is that it fails to provide complex information with a
strategic view.
