A case study on applying clone technology to an industrial application framework

Dealing with clones is a common problem in large-scale software projects. While most of the research in this area is focused on detecting, and investigating the reasons of clones, little research has been done on the use of clone technology in large-scale industrial software. In this paper we present an in-depth case study of cloning in Command and Control Software Framework (CCSF) developed by HAVELSAN, a large software company in the Turkish defense industry. We proposed a practical classification schema for clones based on their removal strategies. A detailed analysis on categorization of clones, and lessons learned in clone management of large-scale industrial software systems are presented.
