Having all of the available facts does not automatically mean that you understand all.
Facts by themselves can and frequently are interpreted in multiple ways dependent on the world view or paradigm that the perceiver works within. Demonstrable in the situation where two individuals, each presented with the same facts, can and do arrive at either different conclusions or make different and possible contradictory decisions.
The provision of an Enterprise Architecture within a business context is an attempt to qualify the facts collected by exposing how they are inter-related. By having a tool that can potentially support predictions on the outcomes of the decision making process the different interpretations of the ‘original facts’ becomes less of an issue.
An Enterprise Architecture can assist in the conversion of knowledge into wisdom with the business gaining significant benefit as a consequence.
