Pathfinder 2: In Situ Design Cost Trades (IDCT) Tool
Abstract
The integration of cost evaluations into the design process, i.e., making them in situ, requires a strategic cost evaluation framework. This framework must address three key components: (1) the processes by which design and cost evaluations are performed, (2) the methodologies/technologies (M/T) that are needed in order to effectively carry out these processes, and more specifically, (3) the way cost models are used, reused, and managed. In order to design in affordability early in design, engineering tools, including cost assessment tools, must be integrated into the design process and interact with tools that support other types of but related, analyses. Insertion of these technologies requires an understanding of the design, requirements, and cost-estimation processes. Therefore, definition of these key processes, and the relationships among the processes, are essential for defining and developing an integrated support tool to enhance these processes. There are many M/T available and being developed to support cost evaluations during design; however, they are not a part of an overall strategy or plan that considers the needs and requirements of the design trade study process and the relationships among the M/T. Models are an important element in cost estimating; they transform parameters and design variables into estimates of cost performance and risk.
