It can run easily on Personal Computers. It has user's friendly interfaces, where project designers can access it through helpful labeled screens and menus. Project estimated size and effort results are obtained in the form of numerical and graphical charts. The tool is tested successfully using several previously data projects. The methodology used is compared with other cost estimation methods.
