One of the most persista

In an effort to maintain an effective, modern force in an acquisition environment constrained by finite resources and rising co

The keystone of the affordability policy is an estimate of the total cost of a program or project over its useful life, i.e. its LCC. Also there is the consideration whether or not one can afford a product which provides a predicted l

The point to be made is that the total cost, not just the initial near term costs, should be considered as an in

Conceptually, then, the evaluation of an acquisition can be considered a two step process. selection of the apparent best alternatives is made, costed out and either accepted or rejected (in part based upon a cost-benefit decision).

Changes in direction and constraints (e.g. quantity, schedule, funding, and mission) occur frequently. Some acquisition elements may not be under the acquisition managers control (e.g. construction, in

An effective LCC management program provides the necessary visibility and the vehicle which enables the acquisition manager to exercise influence over these externally generated costs. One way to approach problems of this type is to use the acquisition LCC methodolog
