This document discusses technology roadmapping and includes examples of roadmaps. It provides a motorola technology roadmap matrix from 1982-1991 that outlines the progression of technologies like tuning, selectivity, displays, and digital modulation for receivers. It also includes a hydrogen fuel cell technology roadmap from 2002-2022 that stages the development of infrastructure, vehicles, and supporting technologies needed to make hydrogen fuel cells viable on a large scale. The document advocates for the use of tools like technology roadmapping, SWOT analysis, gap analysis, and roadmaps to plan and guide research and development initiatives.
