Business process recovery for system maintenance — An empirical approach

Abstract

Understanding business processes is an important step for software maintenance. The approaches for recovering business processes are mostly based on source code analysis, including static analysis and dynamic analysis. All these methods are proved to be effective in some specific situations. However, they are challenged when facing enterprise legacy systems which implement complex business processes triggered by the external actors. In this paper, we introduce a new business process recovery approach that combines the requirement reacquisition with dynamic and static program analysis methods. The approach has been applied to the maintenance of an equity trading system to prove its efficiency.
