Ballpark Figs is a term used to refer to a set of five figures that are used to provide an estimate of the cost of a project. The five figures are STATS (Statistics), ERAS (Estimated Remaining Amounts), HRS (Hours), ESTS (Estimated Time Spent) and MGRS (Managers). These figures are used to give a rough estimate of the cost of a project, and can be used to compare different projects and determine which one is more cost-effective.
