Welcome to the SEVERE Group Website

Our areas of research are software maintenance and software evolution. According to the available data, these two processes consume an overwhelming portion of software engineering resources and therefore a better understanding may have a substantial impact on software quality and productivity. Both software maintenance and evolution are based on repeated changes in the software, where each change typically affects only a small part of software. We are working on developing theoretical models, software tools, environments, and case studies to support these changes.

We are particularly interested in:

  • comprehension of large software
  • concept location
  • incremental change
  • change propagation
  • documentation
  • impact analysis
