This document discusses innovation approaches and the relationship between product management and service design. It provides an overview of each approach, noting their similarities in being agile, customer-centered, interdisciplinary, and iterative. Product management is framed as optimizing individual products or value pools, while service design takes a broader view of optimizing the customer experience across products. The document suggests that product management and service design are complementary rather than competitive, with product management best for optimizing business as usual and service design for addressing significant customer experience gaps across an organization.
