The manufacturing industry is closely connected with product engineering and industrial design. Most manufacturing plants use mass production-including human and robots. A single person can design the product to be manufactured. It takes creativity, problem solving, and decision making to regularly update or make changes in the product. Research teams are constantly looking for ways to improve products and stay ahead of the competition. A business team is also part of manufacturing. A statistician recommends the price for the product after carefully reviewing every expense in producing the product. Marketing and business strategies are also needed to ensure that there will be a constant demand for the product.
