Case Study
Minimizing the Cost of Precision
(The content of this paper is the opinion of Evin Stump, Sr. Systems Engineer at Galorath Incorporated) This paper concerns the cost of adding precision to a product. Most commonly this occurs when precision is needed to make the product meet certain functional requirements. Increased precision typically adds to cost. Of interest is how to achieve the desired product functionality while minimizing cost. The method
used is called variation analysis. To simplify the presentation and make it easier to follow, we present a simple example. Once you understand this example, you may find the method useful in more complex problems.
