The document discusses developing new products and provides guidance on key considerations such as commercial viability, understanding the development process and costs, and a case study of a breast health product called Breastlight. It notes that commercial viability depends on market demand, selling price, profit margin, user benefits, reliability and technology. The development process involves concepts, feasibility studies, design, manufacturing, and commercialization stages. Costs vary significantly depending on the stage from initial concept and research to later manufacturing. The case study then outlines Breastlight's development from concept to commercialization.
