Cost estimating includes identifying and considering various costing alternatives. For example, in mostapplication areas, additional work during a design phase is widely held to have the potential for reducing the cost of the execution phase and product operations. The cost estimating process considers whether the expected savings can offset the cost of the additional design work. Cost estmates are generally expressed in units of(5)to facilitate comparisions both within and across projects. The(6)describes important information about project requirement that is considered during cost estimating.
