Reporting requirements
the quality of existing management reporting systems also effects EIS
software creation. If current reporting systems are high quality, then they
can be used as an effective initial template for EIS reports. EIS is
expected to improve on existing reporting system both in terms of
appearance and functionality. The EIS reporting function can display
graphs, tables and text on single screens, switch between tabular and
graphics output, and attach explanatory notes.
EIS software offers multiple graphs on a single screen for simultaneous
analysis and comparison, high speed presentation of graphs, color coding
to highlight areas of concern, individual color schemes, a variety of
graphs such as pie, bar and line, and automatic generation of scales on
graphs.
