To strive for sustainability under today's intense business competition, organizations apply technology roadmapping (TRM) as a strategic planning tool to integrate their business and technology strategies. Many organizations implement TRM as an ongoing effort. In that case, organizations need to assure that all activities related to TRM implementation are seamlessly integrated with other existing business processes. The consequences of TRM implementation can possibly lead to some changes in the business process, organization structure, or even working culture. Applying change management approach will help organizations to understand the basic elements which an individual needs so that some challenges can be addressed in advance before adopting the technology roadmapping process. This paper proposes a practical guideline to implement technology roadmapping by applying the concept of change management approach. A case example is also included in this paper to present how the subject organization applied change management approach to overcome challenges and limitations occurring during TRM implementation process. The contribution of this paper is to enrich the existing body of knowledge of technology roadmapping with a practical framework to guide practitioners, whom plan to implement TRM processes in their organizations. © 2008 PICMET.
