A structured approach to planning and debugging is obtained by using an Augmented Transition Network (ATN) to model the problem solving process. This proves to be a perspicuous representation for planning concepts including techniques of identification, decomposition and reformulation. It also provides an elegant theory of debugging, in which bugs are identified as errors in transitions between states in the ATN. Examples from the Blocks World and elementary graphics programming problems are used to illustrate the theory.
