For effective decision making, two major inputs are needed. First is the "information" and the second is the "opinions". Information can be compared to the head while opinion can be compared to the heart. Both head and heart should contribute effectively for the right decision to emerge.

Thanks to the mind boggling development taking place in the field of Internet, news, facts, figures, data, statistics etc are available instantaneously across the globe, cutting aside regional and continental barriers.

IT has developed to such a fine level that practically every activity inside the organizations are instantly keyed in to the centralized databases and managers need not really wait for any cutoff date (say month end, half-year closing or financial year end) to get the figures they want.
