An experimental study is presented in which participants perform impact analysis on alternate forms of design record information. The primary objective of the research is to assess the maintainer performance with respect to various approaches of design recording. Among the approaches there is the model dependency descriptor which includes decision capturing and explicit traceability links between software objects and decisions. Results indicate that design recording approaches slightly differ in work completeness and time to finish but the model dependency descriptor leads to an impact analysis which is the most accurate. These results suggest that design records have the potential to be effective for software maintenance but training and process discipline is needed to make design recording worthwhile.
