Patent ID: 8914303

Claim:
A system, comprising: a graphical user interface for receiving user inputted values, the graphical user interface having at least a display device with a grid and a pointer depicted thereon, the grid having a time axis and a value axis, the value axis representing a plurality of user selectable candidate values, said values being a subset of the user inputted values, based on a current position of the pointer on the grid, the pointer being positionable by the user via the graphical user interface; and a data calculator for generating estimates based on the user inputted values, and for generating three curves for display on the grid based on at least one of, the user inputted values and the estimates, wherein the three curves comprise a first, a second, and a third curve representing a triangular distribution and respectively corresponding to expected values for a given item under evaluation, upper bounds with respect to the expected values, and lower bounds with respect to the expected values; wherein said graphical user interface is capable of applying a direct manipulation, based at least on the current position of the pointer on the grid, to at least one of the user inputted values and the estimates, such that a result of the direct manipulation is displayed on the grid, and wherein said graphical user interface enables a user to enter triplets corresponding to an expected value, an upper bound for the expected value, and a lower bound for the expected value, based at least on the current position of the pointer on the grid.
