Project Budget Management is an important part of project planning and execution. Managing a budget refers to managing project estimates, costs and revenues.
Project Budget Management includes the processes involved in planning/estimating costs and controlling costs so that the project can be completed within the approved budget.
Project Budget Management is primarily concerned with the cost of resources needed to complete scheduled tasks, calculated from resource hourly rates and required effort. However, Project Budget Management should also take into account the impact of project activities that have fixed cost, such as services activities, maintenance activities, various decision meetings maintained during the project, etc.
Project cost and project revenue are calculated using different types of resource rates: Cost and Billing rates, correspondingly.
