A method and system for analyzing impact of change in an organizational entity. A graph H includes nets, nodes of the nets, edges connecting the nodes, and edge weights for the edges. The edge weights denote changes in some nodes resulting from changes in other nodes. For a given set Z of nodes A and for each node B characterized by a set S of at least one path of edges connecting nodes of H from node A to node B for each node A of Z, a measure M(Z,B) of a change in node B resulting from a change in each node A of Z is determined. M(Z,B) is a function of the edge weights in each path of S. Each node B of H is displayed via a graphical representation G(B) assigned to each node B. G(B) is a function of M(Z,B).
