ABSTRACT
Why do so many large organizations around the world use parametrics? The reason is to provide speed in estimating the cost and schedule duration when little information exists (see Figure 2.1) regarding a project, proposed program, competitors product or suppliers equipment. During the early stages it is possible to influence the design decisions that are being made and thus reduce the cost of the technology being designed. Parametrics does not necessarily provide more accuracy; although it can contribute when combined with other methods, as we will see in later chapters.
