Figure 1 shows the Network-Centric top level model. Not shown in the drawing is an Information Grid which encompasses all three elements, a Sensor Grid which encompasses the first two elements and an Engagement Grid which covers the last two elements. Sensors and Shooters are classes of objects. Sensor positional data could match the Shooters Frame of Discernment and directly reduce his uncertainty about the location of the target. The fundamental idea is that information is not collected, stored, moved or used to reduce uncertainty.
Information is generated in the course of reducing uncertainty so that decisions can be made.
A decision-maker is presented with data from the world. When his uncertainty has been sufficiently reduced, he will be able to make a decision with confidence. An adversary may use IW Attack measures to interfere with the performance of IW tasks. Corresponding Protect Measures must be used to guarantee that the IW tasks can successfully be performed. In the process of Using data to perform Situation Assessment, Information is generated.
