Product development involves decisions around what to manufacture, packaging, pricing, and sales. The product planner identifies customer needs, aligns capabilities with market demands, and determines if a product is ready to launch or needs more information. New product development consists of creating ideas, evaluating sales potential and profitability, designing production facilities, and marketing the product. The stages include generating ideas, screening ideas, assessing commercial feasibility, product design/evaluation, test marketing, and launching the product. Product failure occurs when a product does not meet sales and profit targets due to declining volume, margins, or higher than expected costs.
