Numerous studies have suggested that the traditional project management tools do not adequately support the coordination efforts required to successfully deliver projects. because they were not developed to control uncertainty which is one of the characteristic of construction project. In traditional construction process control, supervisor usually measures the quantity of production for the project schedule. Flow production has suggested that better productivity, like that labor and cost performance can be achieved by reducing work flows variability. This research has suggested that 1) the circular concept of productivity with work flows variation. 2) the indicators that quantitatively measure work flows variation using productivity data which is obtained from the document of construction field. 3) measurement of productivity-based work flows variation for analyzing correlation with variation of productivity and verifies.
