Product planning is the process of developing a product idea and managing it through launch. It starts with determining corporate objectives and product policy. New product ideas are generated internally from employees or externally from customers, competitors, etc. Ideas are developed into concepts and tested with consumers. Research and development refines the product. Market research including test marketing provides feedback on the product's potential success before a full launch. Proper product planning leads to efficient operations, cost reduction, and avoiding bottlenecks. It is essential for a firm's growth.
