This document discusses developing new products. It begins by defining invention as the discovery of new ideas while innovation is commercializing inventions through bringing them to market. New products are classified as product replacements, additions to existing lines, new product lines, or new-to-the-world products. Successful new product development requires nurturing an innovative culture and organizing effectively using project teams, product/brand managers, new product departments or committees. The process involves idea generation, screening, concept testing, business analysis, product development, market testing, and commercialization while understanding how innovations diffuse through innovators, early adopters, early majority, late majority and laggards.
