Information flow diagram
An information flow diagram is a diagram that shows how information is communicated from a source to a receiver or target, through some medium. The medium acts as a bridge, a means of transmitting the information. Examples of media include word of mouth, radio, email, etc. The concept of IFD was initially used in radio transmission. The diagrammed system may also include feedback, a reply or response to the signal that was given out. The return paths can be two-way or bi-directional: information can flow back and forth. An IFD can be used to model the information flow throughout an organisation.
