摘要：A method for estimating the cost of completion at the end of a first timeinterval of a new program uses a plurality of tasks, program phases and new elements.The estimation steps require making an initial cost allocation for each task within the new
program. Then, tailoring the cost allocation for the program phases to obtain anormalized value. Subsequently, compute a schedule aggressiveness; a requirementsvolatility; and a complexity, where the complexity identifies new elements within the newprogram. Next, combine the normalized value, the schedule aggressiveness, therequirements volatility, and the complexity to extrapolate an end cost for each of thetasks from the initial allocation for the end of the first interval. After summing the endcost for each of the tasks to obtain a first value, adjusting the first value using a resourceneeds ratio and a calibration factor to arrive at an estimated cost of completion of thenew program at the end of the first interval.
