The formulation of an architectural diagram of a software program having multiple components. A static model identifying at least some of the components and a relationship between the components is accessed by perhaps performing a static code analysis of the code of the software program. A dynamic analysis is also performed by executing the software program, and observing the execution to derive dynamic behaviors of the software program. These dynamic behaviors may perhaps be information that is not readily available based on a static code analysis of the computer program alone, such as parameter values exchanged, paths of execution, and additional components invoked. The architectural diagram is then formulated using the static model and the dynamic behaviors to generate a more complete representation of the computer program.
