According to one embodiment of the present invention, a method is present for analyzing a network data processing system. Known information about the network data processing system is obtained by a computer system. A model of the network data processing system is created by the computer system using the known information. Missing information about the network data processing system is identified by the computer system in the model of the network data processing system. A number of people is selected by the computer system for obtaining the missing information. A number of requests to the number of people is sent by the computer system for the missing information. Each request includes the model. In response to receiving a number of responses to the number of requests by the computer system, the computer system updates the model.
