The document outlines a phased product development review process. It discusses four phases: discovery, development, commercialization, and retirement. The discovery phase involves identifying customer needs and opportunities. Development converts specifications into products. Commercialization focuses on customer adoption through introduction, training, and product renewal. Retirement plans for product replacement or discontinuation. A phased review process stops projects from advancing until specifications are stable, improving the chances of success over approaches where projects advance too far without scrutiny.
