Decision making is a promise to act, to do, to fulfill. It is only partially a data processing activity. I see the data processing comparison a lot: ambitious pronouncements that more information, presented more graphically or symbolically, should result in better decisions. Here is an example from something called the RFid Gazette:
"By implementing animated 2-D and 3-D graphics, it will become possible to comprehend large amounts of data quickly; this is because the human mind is more adept at processing information when it is presented in a visual manner. Thus, by implementing information visualization techniques correctly, DoD [Department of Defense] ] hopes to improve the scope of its monitoring, recognize trends in a better manner, and reduce time taken to search and locate. This should ultimately lead to quicker decision making and improved communication."
