Experiences in Architecture Reconstruction at Nokia

This experience report outlines details of past and current architecture reconstruction work on several systems at Nokia. The Dali architecture reconstruction workbench developed by the Software Engineering Institute supported some of these efforts. Other efforts involved various tools and techniques, and in one case, the architecture reconstruction was performed manually. This report describes five such reconstruction efforts and outlines the observations noted and lessons learned while performing them. This report also offers some guidelines for those undertaking a reconstruction effort.
