Requirements changes frequently occur at any time of a
software development process and their management is a
crucial issue to develop software of high quality. Meanwhile,
recently goal-oriented analysis techniques are being
put into practice to elicit requirements. In this situation, the
change management of goal graphs and its support is necessary.
This paper presents two topics related to change management
of goal graphs; 1) version control of goal graphs
and 2) impact analysis on a goal graph when its modifications
occur. In our version control system, we extract
the differences between successive versions of a goal graph
by means of monitoring modification operations performed
through a goal graph editor, and store them in a repository.
Our impact analysis detects conflicts that arise when a new
goal is added, and investigates the achievability of the other
goals when the existing goal is deleted.
