The biggest advantage of product design is that it allows managers to concentrate their expertise on their unique product lines. This leads to a better understanding of the product and its specific requirements, enabling the company to design and manufacture products that are more efficient and effective than those of its competitors. In turn, this can increase market share, revenue, and profits. Low overhead costs, efficient use of functional resources, and encouragement of internal competition are also benefits of product design, but the greatest advantage is the ability of managers to focus on their core competencies.
