A change effort estimation model using impact analysis for the software development phase

Change effort estimation and change impact analysis are two important methods for realizing the consequences of requested changes and make effective change acceptance decisions. Accepting too many changes in the software development phase causes additional cost and delay in the completion. On the ot...
