When a project manager is having issue related to change often in projects how CCB has to reduce pressure on manager?

The selection and prioritization of changes comes from the work performed by the CCB. Changes should be quantified, analyzed and prioritized using some form of a ranking system. Having a pre-defined ranking system will facilitate decision making by making the decision an objective choice, eliminating emotional reactions. Keeping decisions as objective as possible will minimize unnecessary work affecting the overall success of the project.
