Project management involves planning, organizing, and controlling resources to achieve specific goals within constraints of time, cost, and scope. A project has defined objectives, timeline, funding, and consumes resources. Successful project management delivers objectives on time, within budget, and to the required performance level while using resources effectively. Project benefits include improved planning, identification of responsibilities and problems, and better estimates for future projects. Project managers must coordinate with line managers who control resources and balance stakeholder interests for project success.
