What does a project manager ensure regarding project constraints?

A project manager's primary role includes ensuring that all project constraints—such as scope, time, cost, quality, resources, and risk—are effectively managed throughout the project's lifecycle. Proper management of constraints is crucial because they often interact with one another and can impact the overall success of the project. For example, changes to the project scope might affect timelines and budgets, and a competent project manager must navigate these complexities to deliver a successful outcome. By maintaining oversight on constraints, the project manager ensures that the project remains aligned with its objectives and can adjust plans as necessary to address any challenges that arise. This proactive management contributes significantly to the likelihood of achieving the desired project results.
