Project controller

What is the difference between Project Management and Project Control? Project Control is a subset of Project Management whose primary focus is managing the project’s cost and schedule. Project Management directs the project team’s work while the Project Controller advises the team and the Project Manager of possible cost and schedule issues or recovery plans.

If Project Management is about initiating, planning, executing, monitoring, controlling, and closing a project, where does the Project Controller fit?
There is a common misconception about Project Controllers. Since the word “control” in “Project Controllers,” people might think that Project Control is only about controlling and monitoring a project.
The reality is that the Project Controller needs to be involved in the project from its initiation stage to the closure stage to ensure a successful project control implementation.

The Project Manager is responsible for managing the constraints in a project to achieve the result and the objective of a project?
The difference between the Project Controller and the Project Manager goes back to the definition of the role of a Project Controller who defines two primary factors in a project; cost and schedule.

So, who is in charge of the cost and schedule of a project? The Project Controller.
