Computer Assisted Program Understanding systems take input primarily in the form of source code and produce output representing system concepts in some useful form. This paper discusses the development of a program design recovery environment based on structural and behavioral recognition of programming plans. Our research investigates program an d plan representation methods and the issues related t o the detection of code fragments using pattern matching techniques. In particular, we consider the integration of diverse tools allowing selection from a choic e of strategies. Our investigation focuses on technique s to allow partial design recovery when complete recognition is not feasible. Finally, we discuss the underlying process paradigm, called "Goal-Question-Analysis-Action". 1
