1. A method for making a decision when pursuing an overall aim, after discovery of an abnormality in an economic, technical, or organizational field, to counteract the abnormality, the method comprising: associating with a collective knowledge manager a plurality of individual knowledge manager machines, each knowledge manager machine concerning a different point of view determined by the overall aim pursued; establishing a structure of a first knowledge manager machine directly related to the field in which the abnormality has been detected and constituting a first decisional path, the structure of the first knowledge manager machine having a pyramidal shape, with a user manager at an apex, by associating user manager data processing agents located in a plurality of levels of the pyramidal shape, with, in the lowermost of the levels, portable knowledge object creating agents watching actual data in a specific field and detecting abnormalities in the actual data of the first knowledge manager machine, each abnormality detected in the actual data that is being watched, causing in response, creation of a portable knowledge object as an index object, and in the levels above the lowermost level including the knowledge object creating agents, knowledge object constructing agents adding additional knowledge elements to the portable knowledge objects created by the knowledge object creating agents; transmitting the portable knowledge objects from the knowledge object constructing agents to the user manager and transmitting the portable knowledge object from the user manager to the collective knowledge manager; selecting, in response to a request from the collective knowledge manager for further study of the portable knowledge objects constructed in the first knowledge manager machine, at least a second knowledge manger machine from the plurality of individual knowledge manager machines; establishing a structure of the second knowledge manager machine, having a pyramidal shape, similar to the structure of the first individual knowledge manager machine, and constituting a second decisional path with a user manager at an apex, with knowledge object creating agents in a lowermost level of a plurality of levels in the pyramidal shape, and knowledge object constructing agents in levels above the knowledge object creating agents, to achieve the overall aim and results produced by the first individual knowledge manager machine; and providing, in the second knowledge manager machine, the knowledge object creating agents watching actual data and detecting, events related to the knowledge objects created in the first individual knowledge manager machine and, upon detection of an event, creating a knowledge object which is transmitted to the user manager of the second individual knowledge manager machine and to the collective knowledge manager and constructed by addition of additional object elements in the knowledge object constructing agents of the second individual knowledge manager machine to enable the collective knowledge manager to merge results of the first and second decisional paths of the first and second individual knowledge manager machines, to enable a decision for counteracting the abnormality detected.
