The importance of project integration management consists in the need for integrating the project management processes with each other. For instance, a cost estimate necessary for developing acontingency plan involves integration of the time planning processes. It covers high-level management plans such as Cost Management Plan, Time Management Plan and Risk Management Plan. When the manager is able to address most integration management issues, this person unifies and coordinates the constraints (time, cost and risk) and find effective solutions.
Project integration management is important because the manager can combine the deliverables with ongoing operations and create relations between outcomes and strategic expectations. It’s the way to succeed in strategic planning through solving future possible problems and exploiting identified opportunities.
