When Should-Cost models are applied at the early stages of next generation product development, it has the highest potential for cost savings. During the early stages of design, control of part count is paramount to attain the cost targets. Product simplification can be achieved by focusing on part count and part count reduction. This analysis allows designers to determine the theoretical minimum number of parts that must be in the design for the product to function as required. When you identify and eliminate unnecessary parts, you eliminate unnecessary manufacturing and assembly costs, along with “downstream” costs associated with warranty and service, engineering change orders, and utilization of factory floor space.
