The two goals, reduced development time and lowered overall cost, require improved information quality and information management throughout the life cycle, taken in this study as extending from design through field support. This is particularly important during the design phase so that more issues can be considered and analyzed, trade-off studies performed, and design compatibility with subsequent manufacture and product support achieved.

This study investigated the status and interplay of various engineering functions employed over the life cycle of weapons systems to meet the goals more successfully than is done at present. Technology needs and opportunities to promote ULCE for a specific class of applications~dvanced structural components, typical of those employed in high performance aircraft, requiring extremely high reliability and made in small quantities (fewer than 1000)

In the initial phase the following five factors were delineated as independent components of ULCE strategy: design, manufacture, product support, materials, and information flow (see Figure 1-3~. For each area, the practices that constitute the present environment of that area were examined.

UNIFIED LIFE-CYCLE ENGINEERING Two prerequisites that are key to successful ULCE are information quality and information flow at critical junctures during the life cycle of the product. The goal of ULCE must be to provide the information at the inception of design or as close to this as possible, since successful life-cycle engineering requires that all phases of a product's creation and existence be considered when it is designed.

A life-cycle perspective from the designers' vantage point would allow concurrent design processes and thereby reduce the product development cycle time. It would facilitate rapid and efficient response to changes in product functional requirements that inevitably arise during a system's lifetime, and it would enhance the utilization of new technologies.

Figure 1-1 shows the rapid decay of life-cycle cost reduction opportunities early in the product's life cycle. This decay will continue in the future; a majority of the decisions affecting life-cycle performance and cost will be made well before release to production.
