Executive Support Systems

Hi all,
Today i will be talking about Executive Support Systems and how they assist in businesses decision making.
Executive Support Systems like other Information systems turns raw data into useful information, in this case it is used by high level management in areas such as billing and staffing. 
In terms of helping a business ESS turns data into easy to read graphs such as pie charts or histograms. this allows executives to easily take in information and make faster and more informed decisions based on the visual information.

Along with its basic functions stated above ESS also analyzes data and forecasts possible outcomes. While it is impossible to gauge exact outcomes ESS allows for a rough idea of possibilities using statistics and therefore creates better and faster decision making.

Below is a visual of how ESS actually works.

Thank you for reading this.
