Small changes can have major and nonlocal effects in object-orientated languges, due to the use of subtyping and dynamic dispatch. This complicates life for maintence programmers who need to fix bugs or add enhancements to systems originally written by others . Change impact analysis provides feedback on the sematic impact of a set of changes. Moreover if the test fails a subset of changes are responsible for the failure can be identified as well as a subset of changes that can be incorporated safely without affecting any test driver
