In this paper we study the effect of removal of vertices or edges and addition of edges on the independent domination number. Based on the changes, we define six classes of graphs. We investigate the changes and un-changes on certain special class of graphs. We also characterize some of the classes of graphs. Further we obtain some necessary conditions and some sufficient conditions for a graph to be a member of one of the six classes.
