Developing new products is important for business growth and sustainability. There are six categories of new products: new-to-the-world, new product lines, additions to existing lines, improved existing products, repositioned products, and lower-priced products. The new product development process involves strategizing, idea generation, screening, business analysis, development, test marketing, and commercialization. Global issues like adapting products to local needs and finding good ideas worldwide are also considered. New products diffuse through adoption by five categories of users from innovators to laggards based on characteristics like complexity and advantage over existing options.
