In simple terms, Schedule Variance in Project Management is the measurement of the actual progress of a project against the expected progress. Understanding and monitoring the progress of any project is one of the core responsibilities of a project manager. The first step in calculating the Schedule Variance in a project is to establish a set of baselines. These baselines are set for each task within a project and include the projected start and finish dates as well as the budget for each task. These are referred to as the “Schedule Baseline.” From these figures, ongoing comparisons can be used to establish how each task is performing in both time and budgetary aspects.
