It can commence at an early stage or at a much later date during the process which can affect different aspects of project management such as budget and resource planning as well as the quality of deliverables.
The approved change requests review is an important process because it lets everyone in the project know about the changes and how they can adapt to it. While it is often applicable to big changes, minor ones can be implemented by the project leader without seeking approval from the stakeholders.
