An informationflow diagram IFD is an illustration of informationflow throughout an organisation. An IFD shows the relationship between external and internal information flows between an organisation. It also shows the relationship between the internal departments and sub systems. An InformationFlow Diagram is information about a system laid out in diagramatic form. Usually using blobs to explain in more details the system and sub systems to elemental parts. Following on from this you can add in lines of how the information travels from one system to another. This is used in businesses, Government agencies, television and cinematic processes. Overview Peter Checkland , a British management scientist, identifies that information flows between the different elements that compose the system. He also defines a system as a community situated within an environment . IFD is useful for specifying the boundaries and scope of the system. The IFD shows the boundaries and scope of the system, it s interactions with its external entities, and the main flows of information within the system and within any complex subsystems. The InformationFlow Diagram IFD is one of the simplest tools used to document findings from the requirements determination process. They are used for a number of purposes 1. to document the main flows of information around the organisation 2. for the analyst to check that he she has understood those flows and that none has been omitted 3. the analyst may use them during the fact finding process itself as an accurate and efficient way to document findings as they are identified 4. as a high level not detailed tool to document information flows within the organisation as a whole or a lower level tool to document an individual functional area of the business.

The pragmatic theory of information PTOI is a set of concepts and principles for defining, measuring, and tracking the time evolution of information. PTOI is derived from Charles Sanders Peirce s general theory of semeiotic signs and inquiry . Peirce explored a number of ideas about information throughout his career. One set of ideas is about the laws of information having to do with the logic of information logical properties of information . Another set of ideas about time and thought have to do with the dynamics of inquiry dynamic properties of inquiry . All of these ideas contribute to the pragmatic theory of inquiry. Peirce set forth many of these ideas very early in his career, periodically returning to them on scattered occasions until the end, and they appear to be implicit in much of his later work on the logic of science and the theory of signs, but he never developed their implications to the fullest extent. More recently, Edward D. Weinberger formulated a quantitative theory of pragmatic information. In contrast to standard informationtheory that says nothing about the semantic content of information, Weinberger s theory attempts to measure the amount of information actually used in making a decision. Included in Weinberger s paper is a demonstration that his version of pragmatic information increases over the course of time in a simple model of evolution known as the quasispecies model . This is demonstrably not true for the standard measure of information. References Edward D. Weinberger Weinberger, Edward D. 2002 , A Theory of Pragmatic Information and Its Application ...

Refimprove date October 2007 Image Information integration.svg right thumb 400px Schematic Diagram of Information Integration TheoryInformation Integration Theory was proposed by Norman H. Anderson to describe and model how a person integrates information from a number of sources in to make an overall judgment. The theory proposes three functions. ref 1 ref The valuation function V S is an empirically derived mapping of stimuli to an interval scale. It is unique up to an interval transformation y ax b . The integration function r I s1,s2, .. ,sn is an algebraic function combining the subjective values of the information. Cognitive Algebra refers to the class of functions that are used to model the integration process. They may be adding, averaging, weighted averaging, multiplying, etc. The response production function R M r is the process by which the internal impression is translated into an overt response. Information Integration Theory differs from other theories in that it is not erected on a consistency principle such as balance or congruity but rather relies on algebraic models.
