This paper explores the generic concept of affordability analysis, and then discusses the attributes of one method in particular, the Integrated Product and Process Development (IPPD) process. Affordable means obtainable with the means available. Affordability is that characteristic of a system that it does what the customer wants it to do-that is, meets or exceeds the customer's needs-for a price that the customer is willing to pay. An overview of the IPPD process is presented, with emphasis

An example problem involving material specification and selection of the forming process is used to illustrate the technique. It is seen that different "Best-Value" solutions can be achieved at various levels of investment or product cost. The IPPD process will continue to yield advantages to those who use it. This systems engineering approach to Affordability is a discipline to which the De-partment of Defense (DoD) is committed. The Affordability process provides metrics that support making good decisions, understanding ramifications of each option, and drawing upon the collective knowledge of the project team in a structured way. There is now a methodology and associated tools that guide one through the process of creating higher value at a lower cost. During the past decade, customers of aerospace technologies and products have placed ever-increasing emphasis on Affordability. They continue to demand stellar performance, innovative solutions, reliability, and the highest standard of safety-and expect that all will be
