This chapter presents the research on the development of a new concept and methodology called technology development envelope (TDE). TDE approach is applied for identifying the optimum path in developing a technology roadmap in which technology strategies and business strategies are combined. TDE allows the executive-level decision makers in corporations as well as the policy-level decision makers in governments to incorporate disruptive technologies and radical innovations in the development of technology strategies. The combination of Delphi method and hierarchical decision (AHP) is used as a foundation for building the TDE concept. The judgments from technology developers and technology implementers are utilized in the process to assure that the technology strategies are in full support of corporate goals and objectives.
