Product development is the process of discovering valuable, useable, and feasible services. In a how-to format, the author touches on roles/responsibilities, emphasizing the purpose is to determine what (now how) to build; the importance of focusing on the problem that is being solved for the user; the value of high fidelity prototypes (essentially, frequent iterations of the product requirements document); and the implicitly changing nature of product development in consumer businesses. Much of the material is already online, and represents a distillation of consulting engagements.
