Abstract

A method for impact analysis of change requests of a computing system is provided. The method includes, identifying artifacts and tasks that are impacted by a change request on a target project based on a change request repository, an artifact dependency network and a task-artifact mapping repository. The method further includes, determining an impact analysis priority for each of the identified tasks based on associations among the change request and the identified artifacts and tasks, and a project status tracking repository. The method further includes analyzing an impact of the change request on each of the identified tasks according to the determined impact analysis priority. The method further includes obtaining requirements, requirement dependencies and requirement constraints of the project scope to identifying artifacts and tasks that are impacted by a change request on the target project of the project scope.
