Three common resource management techniques include resource forecasting, leveling, and smoothing.
Resource forecasting is a resource management technique that creates a plan of the resources required to deliver a project. It often occurs in the initial phases of a project, even as early as the sales process. A resource forecast estimates the resources and effort that will be required for the project, which helps determine the project timeline, project budget, and the project estimate put forward to the client.
Resource leveling is a technique where you have flexible start and end project dates. This flexibility comes from putting your resources first and trying to level the workload as evenly as you can given your project resources.
Resource smoothing is a bit of the opposite of the leveling technique. In this one, you know you have to finish the project at a certain date and cannot change it. Because time is your priority here, what you do is try to make the most efficient use of your resources. This is accomplished by avoiding peaks and troughs of resource utilization.
